==31928== Your program just tried to execute an instruction that Valgrind
==31928== did not recognise.  There are two possible reasons for this.
==31928== 1. Your program has a bug and erroneously jumped to a non-code
==31928==    location.  If you are running Memcheck and you just saw a
==31928==    warning about a bad jump, it's probably your program's fault.
==31928== 2. The instruction is legitimate but Valgrind doesn't handle it,
==31928==    i.e. it's Valgrind's fault.  If you think this is the case or
==31928==    you are not sure, please let us know and we'll try to fix it.
==31928== Either way, Valgrind will now raise a SIGILL signal which will
==31928== probably kill your program.
