[omniORB] Internal seg fault

[Mike Ladwig]

Hello!

All of my clients crash with a segfault in omni libraries whenever the 
server they are attempting to contact is down.  The client gets the 
objref from NameService, and the problem occurs on the first use of that 
ref.  When the servers are up, things seem to work.

I'm converting a codebase from OMNI 2.7 BOA to OMNI 3.03 POA on RH 
Linux, and probably have messed something up, but not getting an 
exception (the failing call is in a try {} catch (...) {} block) is 
troubling.

Anybody got any ideas?

Thanks,
mike.
