Internal compiler errors with arm-none-eabi-gcc 11.2-2022.02 on Macs with Apple Silicon

Hi,

I just installed gcc-arm-11.2-2022.02-darwin-x86_64-arm-none-eabi.pkg on a Mac with Apple Silicon.
Trying to compile anything, always results in this error: internal compiler error: Illegal instruction: 4
I don't have any of these issues with the previous release of the toolchain (gcc-arm-none-eabi-10.3-2021.10-mac.pkg).
I also tried version 11.2-2022.02 on an Intel based Mac, and there are no compiler errors, as can be seen below.

Any idea what might be causing these problems?

  • Hi community,

    I copy this issue on MacBook Pro M1 Max. Homebrew decided to upgrade the gcc-arm-embedded cask to 11.2, yet compilation seems actually broken now on Apple Silicon. Yes, we can downgrade to 10.3 in the meanwhile, but what is the suggested way to move forward with this?

    Best
