Sounds like you have an easy repro of this - you should be able to debug the problem by attaching the debugger while the program is running and enabling Access Violation to be trapped at the point at which it occurs.

To attach to your process from Visual Studio see here. When you attach to your rogue process, make sure you select the options to debug native and managed code. Make sure symbols for your assemblies and DLLs are available in the Symbol path,as far as you can (some may not be available if they are third-party code).

To alter Exception config so that access violation is debuggable at source, see here.
