The stack you attached above shows a crash during the deallocation of one of our private classes. However, that class is so widely used by our frameworks I don't think the problem is with the class itself but is instead caused by external memory corruption.
Please post the full crash log, using the instructions found here. It's possible the full crash log(s) may provide some indication about what actually created the problem.
