Ahh I read my first post, because it was 5 things. So crash not always happen. It crash sometimes and it must be related with this:
http://talk.remobjects.com/t/vs-probably-memory-leaks/6699
and this:
http://talk.remobjects.com/t/extreme-slowness-in-the-editor-and-memory-loss-reproducible/6575/2
In both cases it’s memory leak problem and at some stage VS just crash. I realized it later, so at day when I create this thread I had internal error and sometimes crash. You cannot reproduce crash, because is random. Try first do leaks (second link - there user attach video) and after try to crash VS
b.r.
