This latest crash is different, a crash during GC mark phase while unwinding the stack looking for roots, because the return address on the stack is invalid. In other words, stack corruption. I wonder whether this is a symptom of the unsound unsafe.Pointer conversions in the windows system call API (https://go.dev/cl/662575)? @qmuntal
