| 4 | at 0x........: main (op_exception.c:30) |
| 5 | Your program just tried to execute an instruction that Valgrind |
| 6 | did not recognise. There are two possible reasons for this. |
| 7 | 1. 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. |
| 10 | 2. 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. |
| 13 | Either way, Valgrind will now raise a SIGILL signal which will |
| 14 | probably kill your program. |
