The attachments here will allow you to demonstrate the following problem.

With glibc-2.2.4-32.8 (on, as it happens, RedHat AS 2.1), if a C++ program 
dlopens a library (the example is python) and then dlopens and calls into a 
second library, and the code in the second library catches an exception and 
then throws that exception in the scope of the block, the catch fails to catch 
the exception and the program aborts.
