Public bug reported:

I encountered a couple strange errors when running unit tests in a C# project that references a C++/CLI project when using static std::strings. I don't know if it is related to NUnit, TestDriven.Net, or .Net itself, but it only happens when running a unit test; I cannot reproduce the problem in a C# console application or C# Windows application. 
 
I have attached a rar archive of a Solution that demonstrates the problem.
 
The TestWeirdError project is a console application and has no problems.
If I comment out line 15 of CppClassForWeirdError.h ("static std::string s ...") or change the string to not be static, then the NUnitTestForWeirdError project works fine, too.
Otherwise, the NUnitTestForWeirdError project generates the following output:
 
 
In Release Mode:
