Bug #: 31276
           Summary: Total Commander 8.0 64-bit installer crashes during
                    cabinet extraction (wrong FCI/FDI structure packing
                    for Win64)
           Product: Wine
           Version: 1.5.9
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs@winehq.org
        ReportedBy: focht@gmx.net
    Classification: Unclassified
Hello,
when bug 30329 is fixed (fix to buggy app installer should be preferred over
Wine) the installer runs into another crash.
The crash is mentioned in this TC thread:
http://ghisler.ch/board/viewtopic.php?p=252389
Trace log doesn't give much useful info because the crash happens within app
supplied FDI notification callback.

It seems the app notification callback code tries to access fdin.psz1 member at
wrong offset (+8).
The FDINOTIFICATION structure:

Looking for other 64-bit apps using cabinet API I found this:
http://www.codeproject.com/Articles/15397/Cabinet-File-CAB-Compression-and-E...
The 32-bit version works ok.
The 64-bit version (Cabinet_x64.exe) exhibits same behaviour, FDINOTIFICATION
psz1 structure member is accessed with wrong offset (+8).
It seems for Win64 the explicit structure packing directives are no longer
applicable and compiler/platform defaults are used (applies for both, fdi.h and
fci.h header).
This allows the installer to succeed.
