my app has started crashing in a very strange place.
i have a custom cell in an outline view... it draws text and with an
icon. In very rare cases, e.g. after running for hours...
I get a segfault (EXC_BAD_ACCESS) with the follow stack trace...
#0 0x706bab64 in objc_msgSend ()
#1 0x70c02778 in -[NSLayoutManager(NSTextViewSupport)
layoutManagerOwnsFirstResponderInWindow:] ()
#2 0x70e4466c in -[NSLayoutManager(NSPrivate)
_drawGlyphsForGlyphRange:atPoint:parameters:] ()
#3 0x70bbcea8 in -[NSLayoutManager(NSTextViewSupport)
drawGlyphsForGlyphRange:atPoint:] ()
#4 0x70e5437c in -[NSStringDrawingTextStorage
drawTextContainer:inRect:onView:pinToTop:] ()
#5 0x70e392e0 in -[NSAttributedString(NSStringDrawing) drawInRect:] ()
#6 0x70be5244 in -[NSString(NSStringDrawing)
drawInRect:withAttributes:] ()
#7 0x0001ab88 in -[ImageCell drawInteriorWithFrame:inView:]
(self=0x2095050, _cmd=0x706e9520, cellFrame={origin = {x = 17, y = 39},
size = {width = 115, height = 17}}, controlView=0x45a8d0) at
ImageCell.m:274
#8 0x0001a3c8 in -[ImageCell drawWithFrame:inView:] (self=0x2095050,
_cmd=0x706e9224, cellFrame={origin = {x = 17, y = 39}, size = {width =
115, height = 17}}, controlView=0x45a8d0) at ImageCell.m:220
#9 0x70ba3444 in -[NSTableView drawRow:clipRect:] ()
#10 0x70bdc34c in -[NSOutlineView drawRow:clipRect:] ()
#11 0x70bba4cc in -[NSTableView drawRect:] ()
#12 0x70c39cf8 in -[NSView _drawRect:clip:] ()
I'm just calling [text drawInRect:rect withAttributes:dict];
and all of text, rect and dict look good in the debugger...
Anyone have a clue what this might be?
thanks!
