FatalExecutionEngineError Managed Debugging Assistant comes up with:

The runtime has encountered a fatal error. The address of the error was at 0x7f578493, on thread 0x14ec. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

(Note 0xc0000005 is ACCESS_VIOLATION).

I doubt I'll get much help but, thoughts?

Also, yes, if I take out the anonymous delegate calls and make those calls inline without a separate thread, the error goes away.

Q: What version of the framework are you compiling on?

[MyndFyre]

I'm compiling to 2.0.

I actually fixed the issue - it was a very, very weird parameter binding issue dealing with using a params[] parameter list instead of a defined parameter list.  Funkified.
