[omniORB] OmniNames crashing

[Bruce Visscher]

Okay, so now we have three different platforms exhibiting this bug.

Since it apparently started happening somewhat recently, perhaps it has
something to do with the introduction of the omniORB_Ripper thread?

Is there any hope that this problem will go away under omniORB 3?

I recall uncovering a problem in this area before, but the design has
changed somewhat since then.

I have noticed that omniNames is moderately recursive in places, so it
is theoretically possible to have a stack overflow if your naming graph
is too deep.  You could try increasing the stack size using the
omni_thread::stacksize member.  OTOH, since you are getting an assertion
failure, this is probably just the application not dying gracefully. 
omniORB 3 seems to be better at this from what I've seen.

No need to appologize, IMHO.  It does seem to be an illusive bug.

All generalities are false - including this one.
