Unexpectedly, Visual Studio 2012 crashes every time I'm trying to debug or build a specific project. That doesn't happen with any other projects of mine, only with this one.

I also noticed that it only crashes when I edit the code. It doesn't crash when I debug without making any changes. Another thing I noticed is that VS doesn't crash if I rebuild the project before debugging.

As I'm keeping backups of the project from time to time, I tried loading the latest one to see if the same thing happens but it doesn't. It debugs and builds without any problem at all. The thing is that I haven't made any noticable changes since the latest backup in order to cause such a problem. The only changes I made were changing the location and adding some controls in one of my forms, editing a simple function and writing a custom combobox in GDI+. That's all!

Is it possible to specify the cause of this problem?
Thanks in advance!
