Could it be some mprotect issue? static-patch is a bytecode that is
used when doing run-time relocations in the .go files, when they are
first loaded up. They are loaded by loader.c. I usually use the mmap
path; is that being used on cygwin? Is it reliable? There is a
fallback path that doesn't use any memory protection. See loader.c.
