[PD] Troubleshooting suggestions

I have a patch that has started to cause a crash in PD. In trying to figure
out exactly what is happening, I reworked the patch, and now each of the
smaller chunks of code are in their own subpatch. So, now the patch doesn't
ALWAYS crash. Now the only time it crashes is when I open the subpatch
containing the offending code, BUT only after that code has been executed at
Lets see if I can give an outline...
1. Open the patch.
2. Setup the patch for operation.
3. Call the subpatch that appears to be cause trouble. Everything executes
properly and does what it is supposed to do.
4. Open the subpatch that contains the troublesome code, and PD crashes
before it can display the patch.
I have checked this in several different versions of PD, from the nightly
builds (ranging from 1129 back to 0927), as well as the 39 extended version.
And all of them crash in the same way.
This is the first time I have run into something like this, and I am not
sure how to proceed in troubleshooting this problem. I looked at the stack
traces in the logs, and everything appears to be PD code that is executing.

I am running on a Mac OS X 10.4.11, while not all of the crashes give the
exact same stack trace, this is the most prevalent one.
