Illegal instruction
I guess I could... I mostly just opened this issue to have a place to upload the files that were produced
I went ahead and changed things from -O3 to -Os for arm64 in dc5906f930b1 to unblock the queue for now.
Fixed upstream now, so we could backport it: https://github.com/llvm/llvm-project/commit/623c4a7a55f7
It looks like changes that claim to fix the original crash have landed upstream, but it also looks like they were too invasive to backport, and instead they are considering reverting the change that introduced the crash in 15.x. https://github.com/llvm/llvm-project/issues/58152
The revert made it into 15.0.3 which is https://github.com/msys2/MINGW-packages/pull/13666
I've reverted the openblas workaround as well in https://github.com/msys2/MINGW-packages/pull/13674
