Unfortunately, the emacs maintainer doesn't have any idea why the recent
emacs changes are causing random crashes on Cygwin. It's almost
impossible to catch this under gdb; and the one time it was caught, the
backtrace didn't make sense. Also, the crash doesn't occur when emacs
is run under strace.
I'm not going to speculate on whether the problem is caused by a bug in
Cygwin's pthread_kill.
