I believe this crash is caused by the same reason of this bug[1]: Somewhere, we have the code that touches stack area that is beyond the red zone. And SIGUSR2 signal stack (that is used to suspend and resume threads, which is heavily used for sampling profiler) mess up these area.

I'll investigate it in this weekend.
