Wow, it's late ... I forgot some of the code in the last email --
here's all of it (still not much, no worries). I see the "program
exited with signal:0" error after this code runs for awhile, and
there's no backtrace.
... and I run a thread to preload the next animation (this code
always preloads the same one, but the idea is that they'll change,
and I don't want to load them all at once and waste memory):
First, "program exited with signal:0" suggests the app was killed by
springboard instead of crashed on it's own. Check the device console
log in the Organizer window and see if it was terminated for a
specific reason. I'm going to guess you used too much memory too
quickly. You have maybe 10 MB of RAM at your disposal on a good day
(on a non-3GS device). Realistically, if you go over 7 MB too quickly
(before springboard can ask other processes to terminate) your process
will be terminated.
Second, UIKit generally isn't thread safe and UIImage is a part of
UIKit. You probably can't safely use it from a secondary thread.
