Bug #: 34120
           Summary: Occasional heap corruption crash during ie7 install
           Product: Wine
           Version: 1.3.10
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

This happened on the sixth run of 'winetricks ie7' without the
WINEDEBUG=warn+heap workaround, so it seems the heap corruption
reported in bug 21947 is still there.  Opening a new bug because
the old one covered multiple problems.
