The debugger component of Visual Studio 2012 is not able to attach to or start one of our own x32 apps written in MS VC++: When the debugger tries to start our app, Visual Studio crashes immediately, before the very first statement of our app even runs.

Our app itself currently runs without problems on Windows XP through Windows 8. VS2005, VS2008 and VS2010 all can be used to debug our app without any problems.

By debugging VS2012 itself with VS2010 (as far as that is possible for me as an outsider) I saw that the program runs into an internal consistency check when trying to free a heap: The heap is considered "corrupted", and devenv.exe terminates. Switching off DEP that seems to help in some such cases does not change anything, neither does running devenv.exe with /SafeMode switch.

I have described the problem and my own investigations so far with many details here:

Many thanks for that fast fix!

I checked today, and indeed both the fallback that you describe and switching to proper string resources for our version info in the .RC file neatly solve all problems with debugging using VS2012.

Thank you for the feedback. I have fixed this for an upcoming visual studio release. The root cause is the version string resources in your binary. For some reason, those strings are listed as binary resources in your pe file. This caused the debugger to choke on those resources. To work around this, you can either make sure these are string resources or if you'd like to leave them as is, you can fallback to the legacy debug engine by enabling native edit-n-continue in tools->options->debugger->native->enable native edit-n-continue.

Thanks again for reporting this
