Arduino IDE compilation (looks like linker) segmentation fault internal error

Hello, im trying to compile marlin software for a 3d printer and flash it to atmega 2560, however when i run compilation for the first time everything works ok, then when i want to compile it again it throws me random errors of internal compiler error: Segmentation fault

}

Most of the time i can handle this by editing faulty cpp file and changing one character that means "}" to "}"

every time i fix one, an restart arduino ide and compile again and works but then after running another compilation without changes everything starts all over again, but in different function.

Didin't know where to post this so maybe developers could find a bug that makes it so i placed that here

cheers

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. It has been reported here: https://github.com/arduino/Arduino/issues/7949

Here's the traditional workaround:

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

Due to a bug, this workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE.

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.

Alternate workaround: One of the Arduino developers recently worked on this and claims to have fixed it. There is a special beta testing hardware package you can install via the Arduino IDE's Boards Manager that has the fix:

  • (In the Arduino IDE) File > Preferences
  • In the "Additional Boards Manager URLs" field, enter: http://downloads.arduino.cc/packages/package_avr_7.3.0_index.json If you already have an additional Boards Manager URL in that field, you can separate multiple URLs with commas or click the button on the right side of the field to open a dialog that allows you to add each on its own line.
  • Click "OK"
  • Tools > Board > Boards Manager
  • Wait for the downloads to finish
  • Click on "Arduino AVR Boards by Arduino"
  • Click the "Update" button.
  • Wait for the update to finish.
  • Click "Close".
