After installing 11.1.060, when I set a breakpoint in other VS2008 projects that only have only C++ code, when debugging and the breakpoint gets hit Visual Studio crashes. Uninstall 11.1.060 and the crashes do not occur. It seems I can debug my FORTRAN projects without problems, but not C++ projects. Is this a known issue? It is very repeatable for me. I'm running on a 64 bit machine, running 64 bit apps. Vista Ultimate 64 is the OS. VS2008 SP1 installed.
