Apologies if this is a re-send; I didn't realize I was sending the
entire crash log to the list!
I have a user of my open-source software who is complaining that the
program crashes when the main window has more than about ~140 items
in its list.
Obviously, the first thing you look at in this case is an array
overrun, but the data array in question is a NSMutableArray so that
seems unlikely to me. In addition, the crash seems to indicate that
it chased a NULL pointer from inside the graphics drawing routines -
can anyone suggest how I can diagnose this problem?
