==21191== Your program just tried to execute an instruction that Valgrind
==21191== did not recognise. There are two possible reasons for this.
==21191== 1. Your program has a bug and erroneously jumped to a non-code
==21191== location. If you are running Memcheck and you just saw a
==21191== warning about a bad jump, it's probably your program's fault.
==21191== 2. The instruction is legitimate but Valgrind doesn't handle it,
==21191== i.e. it's Valgrind's fault. If you think this is the case or
==21191== you are not sure, please let us know and we'll try to fix it.
==21191== Either way, Valgrind will now raise a SIGILL signal which will
==21191== probably kill your program.

I meet a wrong like this, but I don't know the where is the missing.
