[Bug 13269] New: ntdll/tests/exception crashes

http://bugs.winehq.org/show_bug.cgi?id=13269

Summary: ntdll/tests/exception crashes
           Product: Wine
           Version: CVS/GIT
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

test_exceptions crashes in NtSetContextThread on access to the passed CONTEXT.

I have managed to avoid the crash by doing one of the following things:
* Put the CONTEXT on the stack.
* Skip the memset call.
* WINEDEBUG=trace+relay

Toolchain bug?  Wine magic?
