Nice, I'm closing this for now, we can always reopen in case.

I think we'll probably have to wait GCC 12.

hi,
i'm on the new Apple Silicon M1 architecture and using nix emacs-overlay - https://github.com/nix-community/emacs-overlay/
like this: ~/.config/nixpkgs/overlays/emacs.nix
import (builtins.fetchTarball {
url = https://github.com/nix-community/emacs-overlay/archive/master.tar.gz;
})
install whith:
$ nix-env -iA nixpkgs.emacsGcc
it compiles no problem. it runs and bytecompiles everything no problem, but after a while it crashes with:
Assertion failed: (mach_vm_map(mach_task_self(), &address, size, 0, VM_FLAGS_ANYWHERE | VM_MAKE_TAG(VM_MEMORY_COREGRAPHICS_BACKINGSTORES), port, 0, false, prot, prot, VM_INHERIT_SHARE) == KERN_SUCCESS), function backing_map, file /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/SkyLight/SkyLight-569.6/SkyLight/Services/Windows/CGSBackingStore.c, line 192. Fatal error 6: Aborted [1] 2319 abort emacs --fg-daemon
any idea how to investigate?
