// in class declaration (public)
std::vector<std::string> errorArray;

void Engine::AddError(std::string error)
{
	errorArray.push_back(error);
}

I don't see the problem...
Microsoft Visual Studio 6.0 (the best)

Wierd errors...

Have a look here

It's a problem with the debugger that comes with VC++; it cannot handle names longer than 255 characters, which means you can't step through the code correctly when debugging. When doing things with non-trivial templates (which includes the STL) it is possible to exceed the limit of 255.

If you are not planning to step through the offending code with a debugger, you can generally ignore the warning. The warning also won't occur when doing release builds (as one attribute of release builds is turning off debugging support).

As an aside, even Microsoft don't claim that VC++ 6.0 is "the best".
