Is there some reason that you couldn't leave it running once you get
the crash?  If so, perhaps you could describe those reasons, and I
could try helping you overcome them.  Being able to look around in a
crashed session is important for making the debugging as efficient as
possible, given the sporadic nature of the crashes.

Thanks.

Well, if you find some reproducible recipe, it will be appreciated.
