NSSavePanel crashing on instantiation.
-
I am simply throwing up a save panel and doing a runModal on it. I'm
not doing anything fancy at all. I am getting a lot of crashes (not
always) in:
21 com.apple.AppKit 0x92f5852c +[NSSavePanel
_crunchyRawUnbonedPanel] + 0x7c
Any ideas what could be causing this? The app is multithreaded.
However, I have been careful to do all gui operations only in the main
thread. That said, this call to NSSavePanel is done in a method that
is called with performSelectorOnMainThread:withObject:waitUntilDone:
waitUntilDone: TRUE is used of course.

The crashes that are not in this method, where do they pop up?

I hope you got the Monty Python reference? :-)

Could you show a bit more of the backtrace btw.?

Why "of course"? Is the other thread going to do anything with the data
returned from the save panel?
j o a r -
I found the problem. Buffer overrun in one of my threads. I was
stomping on the other threads memory and things were going kablooey all
over the place. :)
