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.
