Bug ID: 53922
           Summary: FoxPro for Windows 2.6a doesn't start when compiled
                    with -O0
           Product: Wine
           Version: 7.20
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

This is how I compile wine for debugging purposes:

ALLFLAGS="-g -O0"
PKG_CONFIG_PATH=/usr/lib32/pkgconfig CC="ccache gcc" CFLAGS="$ALLFLAGS"
CROSSCC="ccache i686-w64-mingw32-gcc" CROSSCFLAGS="$ALLFLAGS"
../wine-git/configure --enable-silent-rules

But when I run FoxPro with that, I get the following output:
> 007c:fixme:hid:handle_IRP_MN_QUERY_ID Unhandled type 00000005
> 007c:fixme:hid:handle_IRP_MN_QUERY_ID Unhandled type 00000005
> 007c:fixme:hid:handle_IRP_MN_QUERY_ID Unhandled type 00000005
> 007c:fixme:hid:handle_IRP_MN_QUERY_ID Unhandled type 00000005
> 00d4:err:seh:KiUserCallbackDispatcher ignoring exception
> 00d4:err:seh:KiUserCallbackDispatcher ignoring exception

Using -O2 instead of -O0 works around that issue.
