+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.
