Strange. Are these user exceptions?  It seems very unlikely, but
perhaps gcc 3.1 has lost the ability to catch exceptions by base class
across shared libraries. You might try a little test program. If that
is the problem, you could rebuild omniORB and all your code, having
commented out the HAS_Cplusplus_catch_exception_by_base define in
include/omniORB4/CORBA_sysdep.h.

Cheers,

Duncan.
