Which version of glib are you using?  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:


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?).
