Crash due to edit.c patch (was: Regression: origin6 crashes with 20050310 (20050211 works))
Hello, as described in http://bugs.winehq.org/show_bug.cgi?id=2813 , Origin6 crashes with the edit.c patch, implementing !ES_AUTO[HV]SCROLL (http://www.winehq.org/hypermail/wine-cvs/2005/02/0506.html). A rather concise but hopefully complete enough trace can be found attached to the bug. Unfortunally, the edit.c patch is too big for me to see anything obvious. Since Origin is of some importance to me, I'm also also willing to pay some bounty for it. Tobias PS: I think there is a further problem burried since even without that patch it won't work - though it doesn't crash (but endless-loops) and proceeds a bit further. I'm trying to nail down the other patch as well (it should be around the same day; unfortunally compiling Wine takes quite long).

I'm pretty certain that this patch just exposes some other bug. The problem is that Origin6 crashes when it receives an EN_MAXTEXT notification. The notification is sent because the text really doesn't fit into the edit control because it's 0 pixels wide. Application creates the edit control with width of -22 and later also tries to resize it to -22, wine turns negative numbers to 0. I would start with writing a test for seting window width & height to negative numbers. good luck. trace: trace:win:WIN_CreateWindowEx (null) "Edit" ex=00000000 style=50000300 3,3 -22x20 parent=0x10084 menu=0x3e9 inst=0x400000 params=(nil) trace:win:dump_window_styles style: WS_CHILD WS_VISIBLE 00000300 trace:win:dump_window_styles exstyle: trace:win:WIN_CreateWindowEx winproc type is 2 (WIN_PROC_32A) trace:win:WIN_SetWindowLong 0x10088 -12 3e9 3 err:x11drv:X11DRV_CreateWindow invalid window width -22 trace:x11drv:X11DRV_set_window_pos win 0x10088 window (3,3)-(3,23) client (3,3)-(3,23) style 40000300 trace:x11drv:X11DRV_CreateWindow hwnd 0x10088 cs 3,3 0x20 trace:edit:EditWndProc_common hwnd=0x10088 msg=81 (WM_NCCREATE) wparam=0 lparam=406eeae0 trace:edit:EDIT_WM_NCCreate Creating ANSI edit control, style = 50000300 trace:win:WIN_SetWindowLong 0x10088 0 4046ad20 3 trace:edit:EditWndProc_common hwnd=0x10088 msg=83 (WM_NCCALCSIZE) wparam=0 lparam=406ee8a0 trace:edit:EditWndProc_common hwnd=0x10088 msg=83 (WM_NCCALCSIZE) -- 0x00000000 trace:x11drv:X11DRV_set_window_pos win 0x10088 window (3,3)-(3,23) client (3,3)-(3,23) style 40000300 trace:x11drv:X11DRV_CreateWindow win 0x10088 window 3,3,3,23 client 3,3,3,23 whole 3,3,3,23 X client 0,0,0,20 xwin 0 trace:edit:EditWndProc_common hwnd=0x10088 msg=1 (WM_CREATE) wparam=0 lparam=406eeae0 trace:edit:EDIT_WM_Create (null) trace:edit:EDIT_EM_SetMargins left=0, right=0 trace:edit:EDIT_SetCaretPos 0 - 0x0 trace:edit:EditWndProc_common hwnd=0x10088 msg=1 (WM_CREATE) -- 0x00000001 trace:edit:EditWndProc_common hwnd=0x10088 msg=5 (WM_SIZE) wparam=0 lparam=140000 trace:edit:EDIT_WM_Size width = 0, height = 20 trace:edit:EDIT_SetCaretPos 0 - 0x0 trace:edit:EditWndProc_common hwnd=0x10088 msg=5 (WM_SIZE) -- 0x00000000 trace:edit:EditWndProc_common hwnd=0x10088 msg=3 (WM_MOVE) wparam=0 lparam=30003 trace:edit:EditWndProc_common hwnd=0x10088 msg=3 (WM_MOVE) -- 0x00000000 trace:x11drv:X11DRV_ShowWindow hwnd=0x10088, cmd=5, wasVisible 0 trace:edit:EditWndProc_common hwnd=0x10088 msg=18 (WM_SHOWWINDOW) wparam=1 lparam=0 trace:edit:EditWndProc_common hwnd=0x10088 msg=18 (WM_SHOWWINDOW) -- 0x00000000 trace:win:SetWindowPos hwnd 0x10088, after (nil), 0,0 (0x0), flags 00000057 trace:win:dump_winpos_flags flags: SWP_NOSIZE SWP_NOMOVE SWP_NOZORDER SWP_NOACTIVATE SWP_SHOWWINDOW trace:x11drv:X11DRV_SetWindowPos hwnd 0x10088, after (nil), swp 0,0 0x0 flags 00000057 trace:edit:EditWndProc_common hwnd=0x10088 msg=46 (WM_WINDOWPOSCHANGING) wparam=0 lparam=406ee810 trace:edit:EditWndProc_common hwnd=0x10088 msg=46 (WM_WINDOWPOSCHANGING) -- 0x00000000 trace:x11drv:SWP_DoWinPosChanging hwnd 0x10088, after (nil), swp 0,0 0x0 flags 00001857 trace:x11drv:SWP_DoWinPosChanging current (3,3)-(3,23) style 40000300 new (3,3)-(3,23) trace:x11drv:X11DRV_set_window_pos win 0x10088 window (3,3)-(3,23) client (3,3)-(3,23) style 50000300 trace:x11drv:X11DRV_SetWindowPos status flags = 1847 trace:edit:EditWndProc_common hwnd=0x10088 msg=47 (WM_WINDOWPOSCHANGED) wparam=0 lparam=406ee810 trace:edit:EditWndProc_common hwnd=0x10088 msg=47 (WM_WINDOWPOSCHANGED) -- 0x00000000 trace:win:WIN_CreateWindowEx created window 0x10088 ... trace:win:SetWindowPos hwnd 0x10088, after (nil), 3,3 (-22x20), flags 0000001c trace:win:dump_winpos_flags flags: SWP_NOZORDER SWP_NOREDRAW SWP_NOACTIVATE trace:x11drv:X11DRV_SetWindowPos hwnd 0x10088, after (nil), swp 3,3 -22x20 flags 0000001c trace:edit:EditWndProc_common hwnd=0x10088 msg=46 (WM_WINDOWPOSCHANGING) wparam=0 lparam=406ee5c4 trace:edit:EditWndProc_common hwnd=0x10088 msg=46 (WM_WINDOWPOSCHANGING) -- 0x00000000 trace:x11drv:SWP_DoWinPosChanging hwnd 0x10088, after (nil), swp 3,3 0x20 flags 0000181c trace:x11drv:SWP_DoWinPosChanging current (3,3)-(3,23) style 50000300 new (3,3)-(3,23) trace:x11drv:X11DRV_set_window_pos win 0x10088 window (3,3)-(3,23) client (3,3)-(3,23) style 50000300 trace:x11drv:X11DRV_SetWindowPos status flags = 1807 ... trace:edit:EditWndProc_common hwnd=0x10088 msg=c (WM_SETTEXT) wparam=0 lparam=40464050 trace:edit:EDIT_WM_SetText L"10" trace:edit:EDIT_EM_ReplaceSel L"10", can_undo 0, send_update 0 trace:edit:EDIT_EM_ReplaceSel inserting stuff (tl 0, strl 2, selstart 0 ('L""'), text 'L""') trace:edit:EDIT_EM_ReplaceSel notification EN_MAXTEXT sent to hwnd=0x10084 fixme:msvcrt:_XcptFilter (-1073741819,0x406ec798)semi-stub wine: Unhandled exception (thread 0009), starting debugger...
