             Bug #: 31360
           Summary: Bobcad v21 crashes on startup
           Product: Wine
           Version: 1.5.9
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com
    Classification: Unclassified


Tried installing v21 express trial from http://www.bobcad.com, sha1sum
2e986bc8e48e74d361a100d0f8ea5f7b1d41c38e  v21.6.exe

Need 'winetricks mfc42' before install to avoid a DLL registration failure.

On startup, the app crashes.  +relay shows it's right after 
ole32.OleCreateEmbeddingHelper() returns.  Adding warn+heap seems to
show it's using freed memory as a pointer:
