Today I have been reported a crash in an application and they sent me the stack trace it captured:11/04/2011 16:09:11 EAccessViolation Access violation Stack trace: $004EED89 $004EF8BD $0040BF3B $004EEBDC $004ED988 $004E532F $004E644E $00567767 $0050D695 $7E418734 $7E418816 $7E4189CD $7E418A10 $00510E34 $00421DB9 $004221AF $0043B473 Address $004EED89 corresponds to this procedure in control.inc (I marked the line with "<----" but I'm not sure the access violation happens there or in the line before). {------------------------------------------------------------------------------ TControl DoMouseUp "Event Handler" ------------------------------------------------------------------------------} procedure TControl.DoMouseUp(var Message: TLMMouse; Button: TMouseButton); var P: TPoint; begin if not (csNoStdEvents in ControlStyle) then with Message do begin if (Button in [mbLeft, mbRight]) and DragManager.IsDragging then begin P := ClientToScreen(Point(XPos, YPos)); DragManager.MouseUp(Button, KeysToShiftState(Keys), P.X, P.Y); Message.Result := 1; end; MouseUp(Button, KeysToShiftState(Keys), XPos, YPos); <---- end; end; The rest of addresses are all in the LCL, leading to this call, starting from $0043B473 which is this procedure in interfacebase.inc: procedure TWidgetSet.AppRun(const ALoop: TApplicationMainLoop); begin if Assigned(ALoop) then ALoop; end; However I have no information for these strange addresses in the middle of the stack: $7E418734 $7E418816 $7E4189CD $7E418A10
Googling for these addresses it seems they are windows' dlls.
Apart from these addresses, everything else doesn't touch my code, so I think that, maybe, it's a bug in the LCL (considering that's quite an old version, Lazarus 0.9.29 r22953 FPC 2.2.4 i386-win32-win32/win64, however it has served me fine in various other projects). What do you think? TIA Bye
