My app enables accessibility and crashes in UIAutomation while releasing some ole acc object.

crash in below callstack:

I need to know which acc client is creating the objects.
How to check all programs installed or running in system that use accessibility or UI automation feature. Can users disable some acc client from accessing my app ?
