Summary: executing old 16-bit program leads to unhandled
                    exception in scroll.c
           Product: Wine
           Version: 20030508
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gdi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

old, 16-bit app crashes every time it gets executed. AFAICS two pointers are
passed to SCROLL_GetScrollRange() function, one of which is truncated to
16-bits, while another stays 32bit wide:

lpMin=0x2428, lpMax=0x415a242c

AFAICS "truncation" happens in function WINPROC_CallProc32ATo16:

11 0x4082a957 (WINPROC_CallWndProc16+0x163(proc=0x4a700dd, hwnd=0x39,
msg=0xe3, wParam=0x2428, lParam=0x415a242c) [winproc.c:255] in user32.dll.so)
(ebp=415a22c0)
  12 0x4082f1fa (WINPROC_CallProc32ATo16+0x66(func=0x4a700dd, hwnd=0x10039,
