runtime: invalid crash stack for morestackc unwind on arm64 mac #65730
Labels
compiler/runtime
Issues related to the Go compiler and/or runtime.
NeedsFix
The path to resolution is known, but the work has not been done.
Milestone
Add this to runtime/proc.go:
Running any program crashes like this, at least on my arm64 mac:
Note that the runtime.oops frame is missing entirely
(runtime.main calls oops calls oopssys calls morestackc during prologue).
Probably the unwinder gets out of sync somewhere around there.
Perhaps the out-of-sync is also the reason for the 'unexpected return pc' failure during unwind.
