Nope, since it's multithreaded. By default, when multithreaded, x264 is 
still deterministic. However, macroblocks in concurrent frame aren't 
encoded in the same order, and frames aren't encoded on the same CPU, so 
crashes due to x264 could occur at different places ( that's why 
multithreaded applications are harder to debug ).

However, a bug usually leads to a crash, not a reboot.

Mathieu
