can you upload your lib for other CSSMers to look at(?)...
eg, here

I'd rather not upload the library as I don't have rights to distribute it. Certainly, this may impact the amount of help you can give me.

Thanks for your suggestions anyways,

In that case, try creating a dummy library that contains a similar example
to your actual code and see if you can reproduce the problem with that
dummy. Tweak the level of similarity until you get something that contains
a bare minimum example with which you can reproduce the problem, and post
that. During the tweaking process, you may even realize what's causing the
problem and/or find an alternate solution that meets your needs while
avoiding this problem.

I'll give this a try. It may take a bit of time to get a copy of the code.
