             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: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com
    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.

Unhandled exception: page fault on write access to 0x00000105 in 32-bit code
(0x7bc4810c).
