Bug ID: 356138
   Summary: vex amd64->IR unhandled instruction bytes 0x8F 0xEA
0x78 0x10 0xD2 0x6 0x6 0x0

Status: UNCONFIRMED
  Severity: major
  Priority: NOR
 Component: memcheck
  Assignee: jsew...@acm.org

==18602== Your program just tried to execute an instruction that Valgrind
==18602== did not recognise.  There are two possible reasons for this.
==18602== 1. Your program has a bug and erroneously jumped to a non-code
==18602==location.  If you are running Memcheck and you just saw a
==18602==warning about a bad jump, it's probably your program's fault.
==18602== 2. The instruction is legitimate but Valgrind doesn't handle it,
==18602==i.e. it's Valgrind's fault.  If you think this is the case or
==18602==you are not sure, please let us know and we'll try to fix it.
==18602== Either way, Valgrind will now raise a SIGILL signal which will
==18602== probably kill your program.
