>==4200== valgrind: Unrecognised instruction at address 0xB94663.
>==4200== Your program just tried to execute an instruction that Valgrind
>==4200== did not recognise.  There are two possible reasons for this.
>==4200== 1. Your program has a bug and erroneously jumped to a non-code
>==4200==    location.  If you are running Memcheck and you just saw a
>==4200==    warning about a bad jump, it's probably your program's fault.
>==4200== 2. The instruction is legitimate but Valgrind doesn't handle it,
>==4200==    i.e. it's Valgrind's fault.  If you think this is the case or
>==4200==    you are not sure, please let us know and we'll try to fix it.
>==4200== Either way, Valgrind will now raise a SIGILL signal which will
>==4200== probably kill your program.
