[omniORB] Core dump within omnithread library

[Adrian Sweet]

Hi,

I've ported a process from OmniORB305 to OmniORB401, and the program now
occasionally core dumps within the omnithread library.
The core file, see dbx output below, show that the program falls over
when trying to delete 'me', comparing this structure with one when the
process is running properly seems to show that the structure has been
corrupted.
I've tried to follow the omnithread library though and I can't see where
the corruption could occur.
Does anyone have any clues on how to track this down, or if it's likely 
to be a bug in OmniORB, Solaris or my program?

The processes are running on a Sun Ultra 2 with Solaris 8.
If you need anymore info please ask.

Thanks,

Adrian
