Re: Seg fault in PortableServer_POA_activate_object function

Lots of things could be causing your segfault, but chances are you
didn't initialize something properly or allocate space for your ev
struct.  It's hard to say without seeing your code.  

A while ago I wrote a similar test program (only for ORBit 0.5.12) with
an interface called Fortune to return fortunes from remote servers.  My
server initialization code looked something like this:

#define THROW if (ev->_major != CORBA_NO_EXCEPTION) {           \
g_error("CORBA Exception:  %s", CORBA_exception_id(ev)); }

...

    /* Initialize the CORBA environment. */

    ev = g_new0(CORBA_Environment, 1);
    CORBA_exception_init(ev);
    THROW;
    orb = CORBA_ORB_init(&argc, argv, "orbit-local-orb", ev);
    THROW;

    /* Snag the root POA and instantiate my server. */
    root_poa = (PortableServer_POA)CORBA_ORB_resolve_initial_references
        (orb, "RootPOA", ev);
    THROW;
    fortune = impl_Fortune__create(root_poa, ev);
    THROW;

Notice two things:  first, I've allocated space for my ev struct;
second, I *always* checked for failures after each ORB call that might
report one...  It's possible you're trying to use the root POA after
having failed to get a reference.
