This happens in a complex scenario with various unit tests running. It only
happens if at least two specific unit tests run together, which both use
DllImport to call native C functions. If I run each of these tests alone, it
completes without this crash.I can duplicate it on my machine, but I cannot
give you the assemblies which caused the crash. But I will provide any further
information as needed.

With Microsoft .NET 3.5, this works without problems.

Reproducible: Always

Steps to Reproduce:
Run unit tests as described in the details. This can only be done at my firm
since I cannot give you the code or the compiled assemblies.
Actual Results:  
Unit test run is aborted with message as described in details.

Expected Results:  
Unit tests are completed correctly.

I use the following additional software:

NUnit 2.5.3.0
Moq 3.1.416.3

The Mono version is 2.6.4, running on a Lenovo Thinkpad T61p with Windows XP SP
3.
