Bug 356611

This happens whenever libld is used to load a dynamically linked library.

==10913== Your program just tried to execute an instruction that Valgrind
==10913== did not recognise.  There are two possible reasons for this.
==10913== 1. Your program has a bug and erroneously jumped to a non-code
==10913==    location.  If you are running Memcheck and you just saw a
==10913==    warning about a bad jump, it's probably your program's fault.
==10913== 2. The instruction is legitimate but Valgrind doesn't handle it,
==10913==    i.e. it's Valgrind's fault.  If you think this is the case or
==10913==    you are not sure, please let us know and we'll try to fix it.
==10913== Either way, Valgrind will now raise a SIGILL signal which will
==10913== probably kill your program.

Reproducible: Always

Steps to Reproduce:
1. valgrind gdb
2. crash



I am using Valgrind 3.11.0 and glibc-2.22 (compiled with -arch=native and -O2)
