3valgrind: Unrecognised instruction at address 0x.........
4   at 0x........: main (op00.c:3)
5Your program just tried to execute an instruction that Valgrind
6did not recognise.  There are two possible reasons for this.
71. Your program has a bug and erroneously jumped to a non-code
8   location.  If you are running Memcheck and you just saw a
9   warning about a bad jump, it's probably your program's fault.
102. The instruction is legitimate but Valgrind doesn't handle it,
11   i.e. it's Valgrind's fault.  If you think this is the case or
12   you are not sure, please let us know and we'll try to fix it.
13Either way, Valgrind will now raise a SIGILL signal which will
14probably kill your program.
