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: wine-bugs at winehq.com
ReportedBy: saulius.krasuckas at elst.vtu.lt
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,
msg=0xe3, wParam=0x415a2428, lParam=0x415a242c) [winproc.c:2738] in
user32.dll.so) (ebp=415a22fc)
