Why can't I return a char* string from C++ to C# in a Release build?

Question

I\'m attempting to call the following trivial C function from C#:

SIMPLEDLL_API const char* ReturnString()
{
    return \"Returning a static string!\";
}
         


        

Answer 1

The C++ compiler in Release mode is putting the constant into the data page, which is protected; attempting to hand this off to C# is causing problems. In Debug mode, the compiler isn't optimizing the constant into the data page, and so there's no protection problem.
