Hi!

This is what I get as an ouput when starting valgrind on my code:

==24908== Your program just tried to execute an instruction that Valgrind
==24908== did not recognise.  There are two possible reasons for this.
==24908== 1. Your program has a bug and erroneously jumped to a non-code
==24908==    location.  If you are running Memcheck and you just saw a
==24908==    warning about a bad jump, it's probably your program's fault.
==24908== 2. The instruction is legitimate but Valgrind doesn't handle it,
==24908==    i.e. it's Valgrind's fault.  If you think this is the case or
==24908==    you are not sure, please let us know and we'll try to fix it.
==24908== Either way, Valgrind will now raise a SIGILL signal which will
==24908== probably kill your program.
