This is odd. I am always loading and closing the IDE while testing things, and I never see this problem.

Hopefully the dump file will offer some clues.

I caught that once more yesterday in different state, VA was already gone when debugger was able to pause the devenv.exe process. There was an exception but the thread died. The remaining threads were in a kind of waiting state. It looked like plugins destruction caused that, while the rest of IDE was waiting for proper closing.
I believe there is nothing special on closing the IDE, I am simply clicking the right-top [X] on the title bar. It is not a logoff or shutdown, just simple application close. I'll try to keep enabling log on closing...

I have the dump file, thank you for this:

case=16357

Have you noticed any form of pattern to these crashes? I am wondering if they might be related to what you are doing before closing the IDE.

Hello feline. Sorry for not providing obvious info.
This is C++ 2003 Standard. That problem appeared several times on different builds, but I was unable to catch it due to fact that my crash handler was set to the IDE. Once VA crashed IDE was unable to start due to locked resources....
That time I had windbg handling crashes.
The size is 40MB after compression with 7z.

The full dump might be useful, how large is it?

Have you seen this problem since? Or was this a one off problem?
Which IDE are you using?
