Hello,
When Visual FoxPro (tested with versions 6 and 7, wine-20040408) tries to open a JPEG file, it crash showing a c0000005 exception. The backtrace of winedbg shows the following API calls:
0 0x407c0e1d (CURSORICON_SimulateLoadingFromResourceW+0x8d(filename=0x403e63b0, fCursor=0x1, res=0x4074a208, ptr=0x4074a20c) [cursoricon.c:512] in USER32.DLL) (ebp=4074a1d0) 1 0x407c1d0d (CURSORICON_Load+0x28d(hInstance=0x0, name=0x403e63b0, width=0x20, height=0x20, colors=0x1, fCursor=0x1, loadflags=0x50) [cursoricon.c:799] in USER32.DLL) (ebp=4074a21c) 2 0x407c4ba0 (LoadImageW+0xb0(hinst=0x0, name=0x403e63b0, type=0x2, desiredx=0x20, desiredy=0x20, loadflags=0x50) [cursoricon.c:2133] in USER32.DLL) (ebp=4074a258) 3 0x407c4a8f (LoadImageA+0x14f(hinst=0x0, name=0x4074a370, type=0x2, desiredx=0x0, desiredy=0x0, loadflags=0x50) [cursoricon.c:2074] in USER32.DLL) (ebp=4074a334) 4 0x407c39b5 (LoadCursorFromFileA+0x45(name=0x4074a370) [cursoricon.c:1649] in USER32.DLL) (ebp=4074a358) 5 0x0053b8c5 (vfp7.exe.EntryPoint+0x13a8c5 in vfp7.exe) (ebp=4074a5e8) 6 0x00490d4b (vfp7.exe.EntryPoint+0x8fd4b in vfp7.exe) (ebp=4074a78c) 7 0x004abd03 (vfp7.exe.EntryPoint+0xaad03 in vfp7.exe) (ebp=4074a928) 8 0x00436a8d (vfp7.exe.EntryPoint+0x35a8d in vfp7.exe) (ebp=0000002b)
The last function (CURSORICON_Simulate...) has a bug that makes the exception when the opened file isn't in RIFF format. Returning with fail when the file is in other format avoids the exception, and Visual FoxPro continue the execution loading correctly the image.
