            Bug ID: 43553
           Summary: ttfautohint compiled with mxe crashes
           Product: Wine
           Version: 2.14
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: wl at gnu.org
      Distribution: ---

Please bear with me, this is, I think, my first Wine bug report.

[wine 2.14, openSuSE Leap 42.2]
[mxe compiling environment: Qt 5.9.1, gcc 5.4.0]

My self-compiled ttfautohintGUI.exe program using the mxe cross compiling
environment under GNU/Linux crashes with wine as follows.

  wine: Unhandled page fault on read access to 0x00000004 \
        at address 0x7ecccfce (thread 0009), starting debugger...
  winedbg: Internal crash at 0x7e88bfce

Running the program directly with `winedbg' returns

  Unhandled exception: page fault on read access to 0x00000004 \
                       in 32-bit code (0x7ecccfce).
