[Bug 28735] New: ntdll/tests/exception.ok fails under valgrind

http://bugs.winehq.org/show_bug.cgi?id=28735

Bug #: 28735
           Summary: ntdll/tests/exception.ok fails under valgrind
           Product: Wine
           Version: 1.3.30
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Running "make exception.ok" in ntdll/tests under valgrind fails.
This has been happening since at least early last year.  Log:

valgrind: Unrecognised instruction at address 0x7f230000.
Your program just tried to execute an instruction that Valgrind
did not recognise.  There are two possible reasons for this.
1. Your program has a bug and erroneously jumped to a non-code
   location.  If you are running Memcheck and you just saw a
   warning about a bad jump, it's probably your program's fault.
2. The instruction is legitimate but Valgrind doesn't handle it,
   i.e. it's Valgrind's fault.  If you think this is the case or
   you are not sure, please let us know and we'll try to fix it.
Either way, Valgrind will now raise a SIGILL signal which will
probably kill your program.

Might be a valgrind bug, but winehq is probably the right place for triaging
it.

Same cause as bug 20985, perhaps?

I'm seeing something similar in ddraw/tests/drawmodes.ok:

Unhandled exception: illegal instruction in 32-bit code (0x00000000).
...
Backtrace:
=>0 0x00000000 (0x7f23fc88)
  1 0x049b77f5 test_DirectDrawEnumerateA+0x5b()
[dlls/ddraw/tests/ddrawmodes.c:140] in ddraw_test (0x7f23fcb8)
...
err:seh:segv_handler Got unexpected trap 0

The test and valgrind finish, but with exit status 29.

What about this bug with current wine(3.20)?

Still occurs in 4.10.  An even simpler test case: compile 'int main() { return
0; }' using mingw and wine it under valgrind.  Valgrind prints an error that it
has encountered an unrecognised instruction inside of set_cpu_context
(signal_x86_64.c).

That attachment doesn't show the test running under valgrind, rather running as
usual.

It seems to be caused by the iretq instruction.
