I think it is an already reported (but still not fixed) bug. E.g.:
http://www.omniorb-support.com/pipermail/omniorb-list/2002-September/021810.html
Another solution (which does not involve modifications in omniORB's 
source) is to implement your own sslContext::singleton, instantiate it 
statically (if not - delete it before calling orb->destroy()) and put 
the proposed code in its destructor.
