Check out the C bindings chapter in the CORBA spec. Specifically
section 19.11.

Basically calling CORBA_free() on the sequence will free _buffer if 
you have called CORBA_sequence_set_release (sequence, TRUE).
The default value is false, so if you allocate the buffer with your
allocbuf() function and don't call set_release you end up leaking
memory most of the time.

The _release field there is ORBit-specific, to be portable across ORBs
you are supposed to call the get/set release functions.
