I try to comment the following code in cpu.cpp (line 190-215) and it works. Though I don't understand why it works.

// static LONG CALLBACK catch_sigill(struct _EXCEPTION_POINTERS* ExceptionInfo)
// {
//     if (ExceptionInfo->ExceptionRecord->ExceptionCode == EXCEPTION_ILLEGAL_INSTRUCTION)
//     {
//         g_sigill_caught = 1;
//         longjmp(g_jmpbuf, -1);
//     }

//     return EXCEPTION_CONTINUE_SEARCH;
// }

// static int detectisa(const void* some_inst)
// {
//     g_sigill_caught = 0;

//     PVOID eh = AddVectoredExceptionHandler(1, catch_sigill);

//     if (setjmp(g_jmpbuf) == 0)
//     {
//         ((void (*)())some_inst)();
//     }

//     RemoveVectoredExceptionHandler(eh);

//     return g_sigill_caught ? 0 : 1;
// }
