Bug 285725

Version:           3.6.0
OS:                Linux

Valgrind always terminates with an unhandled instruction error:
'vex amd64->IR: unhandled instruction bytes: 0xC5 0xF9 0x28 0xD0 0xC5 0xFB'

Reproducible: Didn't try

Steps to Reproduce:
'valgrind ./foo'

Actual Results:  
Console output as below:

vex amd64->IR: unhandled instruction bytes: 0xC5 0xF9 0x28 0xD0 0xC5 0xFB
==23054== valgrind: Unrecognised instruction at address 0x7213f54.
==23054== Your program just tried to execute an instruction that Valgrind
==23054== did not recognise.  There are two possible reasons for this.
==23054== 1. Your program has a bug and erroneously jumped to a non-code
==23054==    location.  If you are running Memcheck and you just saw a
==23054==    warning about a bad jump, it's probably your program's fault.
==23054== 2. The instruction is legitimate but Valgrind doesn't handle it,
==23054==    i.e. it's Valgrind's fault.  If you think this is the case or
==23054==    you are not sure, please let us know and we'll try to fix it.
==23054== Either way, Valgrind will now raise a SIGILL signal which will
==23054== probably kill your program.
