Here's a better description: after stepping into the code line by
line.
Upon creation, with eq::getConfig() server has a refcount of 1
with my program it has a recount of 0.
And.. at this point in the code (where it hangs)
eq::Client::connectServer(ServerPtr server) {
...
if( connect( net::NodePtr( server.get( )) ))
...
}
de-references the ServerPtr, after it's use of server.get()
When created with eq::getConfig() server has at this point a refcount
of 3
When created with my program, server has at this point a refcount of
1, and since refcount hits 0 during de-ref it calls
deleteReferenced(this) on the line of code in ConnectServer above.
I'm not sure if I can increment RefCount on my own - just to test it?
I'm not very gc savvy.
-S!
ALso, when debugging and looking at server._ptr->getRefCount() I get
stuff that looks like this when I run it from eqOsirix and not
eq::getConfig()

When run from eq::getConfig() I get a happy little
(gdb) p server._ptr->getRefCount()
$1 = 2
which makes me thing that I'm missing an #include or something, since
(gdb) doesn't have the all the symbolic information.
Hopefully that's informative enough to work on.
-S!
