| valgrind: Unrecognised instruction at address 0x......... |
| at 0x........: main (op_exception.c:30) |
| Your program just tried to execute an instruction that Valgrind |
| did not recognise. There are two possible reasons for this. |
| 1. Your program has a bug and erroneously jumped to a non-code |
| location. If you are running Memcheck and you just saw a |
| warning about a bad jump, it's probably your program's fault. |
| 2. The instruction is legitimate but Valgrind doesn't handle it, |
| i.e. it's Valgrind's fault. If you think this is the case or |
| you are not sure, please let us know and we'll try to fix it. |
| Either way, Valgrind will now raise a SIGILL signal which will |
| probably kill your program. |
