Ok, that's a commercial app. I though it was only a prototype.

I would expect that LLVM’s exception handling is pretty well broken-in by now, considering the volume of Obj-C and C++ code that Apple has shipped using it so far. Which isn’t to say that that couldn’t be the problem, but I don’t want to annoy users by putting out a bunch of releases that apparently are unchanged while I blindly flail about behind the scenes, hoping something fixes it.
By the way, both thread 0 and 2 seem to be in the same routine by the time it crashes. Are you sure all your variables are thread safe?
