Segfaults in x86 if compiled with dynarec support #256

Open sergiobenrocha2 opened 9 years ago

sergiobenrocha2 commented 9 years ago

It's segfaulting if you compile it with dynarec support for x86, and try load a game with mupen64-cpucore = "cached_interpreter":

Program received signal SIGSEGV, Segmentation fault.

With "mupen64-cpucore = dynamic_recompiler" it will shows only a black screen, but you can back to RGUI.

Tested on ubuntu 14.04
