Hoping that someone could shed some light on my problem. I'm currently teaching a Grade 9 arduino course using Chromebooks and arduino-compatible UNOs. Things have been going very well for the past two months and students have really gotten into building circuits and writing code on Arduino Create's online IDE. However from Thursday last week, students have not been able to get their code verified using the Arduino Create online IDE. I had students try using code which worked previously but they continue to get the same error message despite the code being free of errors.
Here is the following error message that I get when trying to verify code:
./opt/arduino-builder/arduino-builder -compile -core-api-version 10611 -hardware opt/arduino-builder/hardware -hardware ./opt/cores -tools opt/arduino-builder/tools -tools ./opt/tools -built-in-libraries opt/libraries/latest -logger humantags -fqbn arduino:avr:uno -build-cache /tmp -build-path /tmp/733499762/build -verbose -prefs runtime.tools.avr-gcc.path=./opt/tools/avr-gcc/5.4.0-atmel3.6.1-arduino2 -prefs runtime.tools.avrdude.path=./opt/tools/avrdude/6.3.0-arduino14 -prefs runtime.tools.arduinoOTA.path=./opt/tools/arduinoOTA/1.2.1 -libraries /tmp/733499762/custom -libraries /tmp/733499762/pinned /tmp/733499762/sketch_sep17a
Linking everything together...
lto1: fatal error: bytecode stream generated with LTO version 3.0 instead of the expected 4.1
lto-wrapper: fatal error: ./opt/tools/avr-gcc/5.4.0-atmel3.6.1-arduino2/bin/avr-gcc returned 1 exit status

exit status 1
I'm unsure what to do and suspect that there is a problem with the Arduino Create online IDE. Any help would be greatly appreciated!
