Bug #: 28714
           Summary: vbscript/run.ok: invalid write in DispatchEx_Release
           Product: Wine
           Version: 1.3.30
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal

         Component: vbscript
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Looks like valgrind caught some wild pointer references:

etc.  There are about 24 of these errors.

The patch seems to work - I saw no valgrind errors in vbscript after
applying it.  Thanks!
