If you get the chance, when you encounter something like this that is reproducible (or at least seems obvious what's going on), you can use the Report a Problem tool and capture as many relevant diagnostics as possible. I don't work on the C++ tools team, but generally the folks working on VS are highly interested in getting detailed bug reports.
