IDE 1.8.6 - SD-Lib "Datalogger" - segmentation fault #7949

mikrocoder · 2018-08-29T20:35:30Z

Hallo,

I have the following sporadic error. Memory is checked with Memtest and okay.
If I copy the sketch into a new window, no errors will occur.
With the older SD-Lib version of IDE 1.8.5 compiles without errors under the new IDE 1.8.6
Windows 10 64Bit

Arduino: 1.8.6 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

A previous "Segmentation fault" issue report:
#7946

I've also encountered sporadic errors similar to this while using the Arduino AVR Boards 1.6.20x beta releases. I was never able to produce a MCVE. The problem would go away after I restarted my computer. The problem did not occur when the same code was compiled with Arduino AVR Boards 1.6.21.

mikrocoder · 2018-09-05T11:30:54Z

I have switched back to version v1.8.5 now.
I hope it is fixed in the next version.

PaulStoffregen · 2018-09-05T11:38:51Z

I tried it just now on Windows 10 64 bit with Arduino 1.8.6 using AVR core 1.6.22.

Clicked Verify a dozen times. All worked perfectly.

mikrocoder · 2018-09-05T15:38:12Z

I can't say otherwise how it is. v1.8.5 works without errors and 1.8.6 with sporadic errors with this example. I've never had a segmentation error before. Possibly a rare error in the new toolchain version. I'm also not the only one with the segmentation fault problem. https://forum.arduino.cc/index.php?topic=566826.0

Additional question. Why is the variable pathidx not initialized in SD.cpp?

qbahn21 · 2018-09-19T19:44:42Z

Confirm. I've also experienced such a sporadic errors with 1.8.6 toolchain. 1.8.5 works great!

per1234 · 2018-11-29T08:51:58Z

I'm going to start a list of the reports of this issue in case it helps with the investigation:

In all cases, the OS is Windows.

I'll continue to add to the list as additional reports come in.

facchinm · 2018-11-29T14:11:18Z

@per1234 I'm investigating the issue by bisecting Atmel patches and vanilla gcc versions. It could take a bit. Reproducing consistently on all OSes with this sketch arduino/ArduinoCore-avr#39 (when that will be fixed I think also this issue could be automatically solved).

facchinm · 2018-11-29T19:49:29Z

Here's a json ready for testing for all host OS (http://downloads.arduino.cc/packages/package_avr_7.3.0_index.json). It will trigger an update to avr core 1.6.208.

The build is based on vanilla gcc since Atmel patches for 5.4.0 break an internal sanity test when finalizing the build (didn't have the time to try to fix it yet). The missing Atmel patches are likely to break or limit support for ATTiny so DON'T USE THIS THING IN PRODUCTION 😄

However, all other boards should be supported (~~avr4809 too~~). This toolchain fixes arduino/ArduinoCore-avr#39 while I couldn't reproduce #7949 so I hope you can test it and report back.

@matthijskooijman do you still have the mass builder script with all the fancy statistics lying around? It would be cool to have a 4.9.2 vs 5.4.0 vs 7.3.0 😉

EDIT: avr4809 (architecture avrxmega3) support needs Atmel patches, so right now the toolchain is just suitable fol classic ATMegas.

mikrocoder · 2018-11-30T15:14:37Z

I have tested ArduinoCore version 1.6.23.
https://github.com/arduino/ArduinoCore-avr
and then compiled the Sketch SD-Datalogger countless times.
No segemantation errors so far. 👍

matthijskooijman · 2018-11-30T21:56:36Z

@facchinm, Nice to see a vanilla gcc. If we can get that to work (possibly with some patches applied upstream), that would totally rock over having to wait for atmel all the time :-)

As for the builder script, it's here: https://github.com/matthijskooijman/arduino-mass-builder
I haven't used it anymore since I first wrote it, but I suspect it still works :-)

facchinm · 2018-12-03T14:19:33Z

I've just updated the toolchain to arduino4 with all (I hope 🙂 ) the Atmel patches included. AVR core gets updated to .209 ; compiling for 4809 is now possible, although the megaAVR core needs an extra patch (the toolchain version in use is hardcoded in platform.txt).
@matthijskooijman I'll launch the mass builder soon, thanks for the link 😉

Patches here: https://github.com/arduino/toolchain-avr/tree/staging/avr-gcc-patches

per1234 · 2018-12-03T14:36:36Z

I've been hoping to check whether the new toolchain fixes the segmentation fault but I haven't been able to reproduce that bug even with Arduino AVR Boards 1.6.23, despite compiling multiple sketches that have caused it for me in the past on and off. It's really a pain of a bug.

I have been using Arduino AVR Boards 1.6.208 (and now 1.6.209) with no problems since it was published. I'll be sure to report if I discover anything of note.

mikrocoder · 2018-12-07T22:39:06Z

I tested the datalogger example with IDE v1.8.8, couldn't provoke a segmentation error. :-)

ImpulseAdventure · 2018-12-20T08:44:35Z

Another validation datapoint: I had reported a similar crash with lto, gcc 5.4.0 & Windows in arduino/ArduinoCore-avr#55.

@facchinm -- upon retesting with the revised package json with AVR boards 1.6.208 & IDE 1.8.7, I'm happy to report that I no longer observe the compiler crash.

As a reference for others, here is the simple testcase I constructed for the bug, using a couple structs and an extern "C" wrapper: https://github.com/ImpulseAdventure/Arduino-LTO-Error

Psychokiller1888 · 2019-01-08T16:39:25Z

Same here, randomly happens. Since today impossible to compile at all anymore, where I could sporadically compile before

This version is recommended with Arduino 1.8.8 or newer due to some issues with the new compiler on older versions: arduino/Arduino#7949. Updated AVR-GCC compiler (5.4.0-atmel3.6.1-arduino2) and AVRdude uploader (6.3.0-arduino14) with the latest for the moment. Changed some flags and options into platform.txt. Added support and example sketches for Olimex board eduArdu.

Might be code-length dependent. I couldn't get it to fail with the Blink sketch, failed about 1 out of 5 with this sketch, and 8/10 on my 3K+ line sketch

Just started happening yesterday and today. Not sure why.

FYI @facchinm & @per1234 -- in case it is helpful to have a very minimal test sketch to reproduce the LTO failure in IDE 1.8.9 w/o any other dependencies, please see: Arduino-LTO-Error.

For the benefit of others looking for a solution (without rolling back to an older version):

The workaround of installing package_avr_7.3.0_index.json with latest Arduino AVR Boards (1.6.209) resolves the issue:
- Add http://downloads.arduino.cc/packages/package_avr_7.3.0_index.json to the Preferences -> Settings -> Additional Boards Manager URLs
- In Tools -> Board -> Boards Manager, locate Arduino AVR Boards and click on Update. This should be reflected as version 1.6.209.
- Note that it was cautioned earlier that this workaround is not intended for production.
- Special thanks to per1234 for identifying occurrences of the issue in various repos and highlighting the workarounds

MartyMacGyver · 2019-09-08T05:21:38Z

It's been just over a year now. Is anyone officially working on this issue so it can be resolved in the main Arduino toolchain versus the "don't use in production" workarounds?

mikrocoder · 2019-09-08T15:13:07Z

Well, guys, I wasn't taken seriously back then. Neither here nor in the Arduino Forum. Can only say uses a current toolchain.

MartyMacGyver · 2019-09-21T04:43:42Z

@mikrocoder Looks like that's changed now - give 1.8.10 a try, and be sure to update your board compilers via the boards manager.

ImpulseAdventure · 2019-09-21T06:19:07Z

Fantastic! Arduino IDE 1.8.10 (with Arduino AVR Boards 1.8.1) appears to have resolved the LTO issues I had previously observed in my testcases.

@facchinm & the rest of the Arduino team -- thank you very much for the fix!

mikrocoder · 2019-09-21T10:09:50Z

Nice. I'm about to test it. What was fixed is unfortunately not in the release note. Although I now use a current toolchain.

MartyMacGyver · 2019-09-21T18:17:38Z

You need to download the latest board package via the boards manager after the install, but it's from the official source now, isn't it? Or does it depend on the alternate source still?

facchinm · 2019-09-23T07:24:14Z

@MartyMacGyver it's official now; the relevant part of the changelog is here (should backport to avr repo)

MartyMacGyver · 2019-09-23T07:35:52Z
