==23501== Your program just tried to execute an instruction that Valgrind
==23501== did not recognise.  There are two possible reasons for this.
==23501== 1. Your program has a bug and erroneously jumped to a non-code
==23501==    location.  If you are running Memcheck and you just saw a
==23501==    warning about a bad jump, it's probably your program's fault.
==23501== 2. The instruction is legitimate but Valgrind doesn't handle it,
==23501==    i.e. it's Valgrind's fault.  If you think this is the case or
==23501==    you are not sure, please let us know and we'll try to fix it.
==23501== Either way, Valgrind will now raise a SIGILL signal which will
==23501== probably kill your program.
==23501== Warning: client switching stacks?  SP change: 0x5e5d2b0 -->
0x7feffeee0
==23501==          to suppress, use: --max-stackframe=34244009008 or greater

This error is not reproduced in Debian Sid's valgrind 3.9.0-5.

Reproducible: Always
