x86_64 darwin fails on the arm64 CI runner using `arch -x86_64 make [...]`

[attila-lendvai]

it works fine in an x86_64 macos running in kvm on linux.

is this an x86 simulator bug? or something in maru?

the sigsegv at the end could be a stack overflow while printing the backtrace, but does that really eat more stack than the GC?.
