Bug #: 34570
           Summary: Game crash because of improperly cloning MMIOINFO
                    struct in MMIO_Open
           Product: Wine
           Version: 1.7.2
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winmm&mci
        AssignedTo: wine-bugs@winehq.org
        ReportedBy: jiashulu@gmail.com
    Classification: Unclassified

A quick fix
The game "Custom reido F" crashes on start.
The problem is that the whole adwInfo[] array in MMIOINFO struct is used by the
game, but wine only clones adwInfo[0] in MMIO_Open. A quick fix is attached.
What is more, I checked MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/dd757322%28v=vs.85%2...
and found that adwInfo[] array should have 4 elements instead of 3 in wine.
This perhaps will cause problems in other programs. I am not sure which APIs
are affected by this.
