A crash in _CFDictionaryGrow suggests to me that your app has used up
all the memory available to it. Does anything in your user's console
log indicate this? If you're doing batch operations on a background
thread, are you sure it's managing its memory properly?

I recently released a universal binary to beta testers. My
application does offline batch processing on audio files, using the
Audio Units framework. In general, the process takes about 5 minutes
per file, so I do this work in a separate thread. One of my users
reported that the application crashed while about half way through
the 15th file (of 24). He was able to resume his batch from that
file, and complete it successfully.
I have not been able to make heads or tails of this crash dump
(below). I was hoping someone could point me in the right direction.
It appears that none of it is really my code. What is the start/
_start method? Some sort of auto-generated entry point? The
application is in Objective-C++.
My tester has a PPC mac, and I an Intel (so this crash happened on
PPC).
Thanks in advance!
