http://bugs.winehq.org/show_bug.cgi?id=27577

Summary: Starting apps via winedbg leads to reproducible app
                    crash
           Product: Wine
           Version: 1.3.22
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winedbg
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

To reproduce, install e.g. windows version of GIMP.
Start it this way:
winedbg gimp-2.6.exe
It begins working, then crashes with this output:

WineDbg starting on pid 0029
First chance exception: page fault on write access to 0x003c0000 in 32-bit code
(0x7e77a3d7).

The crash on write access to 0x003c0000 (0x00340000 on another machine) seems
to be always the same across applications. And, if started via wine instead of
winedbg, they work perfectly. Also, if i quit debugger after the crash using
"q" command, the app continues to work normally.

This is just a DIB section access, which is perfectly normal and has no impact
on the application execution. You can configure winedbg to ignore first-chance
exceptions or just pass the exception when it occurs.
