You don't say what target CPU you are using and that is important here as
toolset target specific configuration issues have to be addressed to make
this work.

There are/were known problems throwing C++ exceptions that had to be
addressed to get omniORB working with RTEMS.  Rosimildo DaSilva
<rdasilva at connecttel.com> worked on this and made an announcement on
rtems-list this week regarding this.  I recommend you check out his web
site on the port:
