[tao-users] CORBA::ORB_init leaks memory?

[Johnny Willemsen]

Hi,

Probably you are not releasing all CORBA references or made an error
with the usage of var/ptr/duplicate. When you run the TAO/tests/Hello
test you should see no valgrind leaks (at least it doesn't do with the
latest micro). Try to just do a CORBA::init and a shutdown, that should
be leak free.
