How to reproduce:
Compile this code

void setup() {
Serial.begin(9600);
}

float i = 0;
unsigned long t0 = 0;
void loop() {
i += 1.0;

if (millis() - t0 > 1000) {
Serial.println(i);
t0 = millis();
}
}

Closing as duplicate of #7949

This bug is specific to the 5.4.0-atmel3.6.1-arduino2 version of avr-gcc used by Arduino AVR Boards 1.6.22 and newer.

Here's the traditional workaround:

1. Tools > Board > Boards Manager
2. Wait for downloads to finish.
3. When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
4. Click "Install".
5. Wait for installation to finish.
6. Click "Close".

If you have File > Preferences > Check for updates on startup checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again.
