Older versions require special handholding with initialization, e.g., g_type_init, and perhaps we're running into that problem -- or perhaps you're using a newer version and its autoinitialization code isn't working. Also, a bit of Googling found this bug: http://cygwin.com/ml/cygwin/2012-05/msg00472.html where signals may nor may not reach the correct thread with pthread_kill. Emacs uses pthread_kill to redirect SIGCHLD to the main thread; if this is sent to a random thread instead, that could explain the random crashes you're observing (maybe a recursive runaway in a signal handler?).
