initialization fails

Hello,
in a project I have to use an endpoint to initialize the ORB. If the
initialization is successful everything is fine. If the initialization fails
(because the port is already occupied) memory is leaked as shown by the
following run with valgrind:

In order to reproduce the problem please compile and run the attached program
via the runOrbTest start script (perhaps the LD_LIBRARY_PATH and/or the path
to valgrind has to be changed) in two different shell windows. The program
instance which is started first will use port 50000. After initializing the
orb the program will sleep for 20 seconds and then terminate. This program
instance shows no leaks. If a second program instance is started during the
20 seconds period it will fail to bind the port 50000 and then terminate. Its
the second program instance which shows the leak above.
Best regards,
Martin
