[omniORB] application crashes during ORB shutdown

[Serguei Kolos]

Hello

I have encountered a strange problem while doing shutdown
at the end of my CORBA application. My program crashes with
segmentation fault, but not in the main thread (where the shutdown
is called) but in the other thread. The stacks for the crashed and
main threads are shown at the end of the message.
If I don't call the shutdown method I don't have this problem.
With the call to shutdown the problem is easily reproducible.

I'll be very glad for any hint.

I'm using omniORB 4.0.2 on RedHat 7.3 with gcc2.95.2

this is stack of the faulty thread:
