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: 4I 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?
Best regards,Derek
Hi Tamar,thank you for the reply.I thought so too, maybe some AVX vector instructions.
Do you know if there is any plan to solve this problem?If so, can I be of any help?
