This is a hunch, but is it possible GC is somehow triggered either on a secondary thread or in an event handler? Can you uncomment the definitions of NSTRACE_ENABLED and NSTRACE_ALL_GROUPS in nsterm.h and post the last few lines produced that way before a crash? Also, what's the output of "i thr" in gdb after that crash?
