I'm sorry, but I had to pull ORBit out because I really needed 
threading. I'm still using ORBit in my server though, but that doesn't 
use Qt. :) I replaced it with omniORB 4.0.

The goods news is, is that it worked flawlessly without threads. I just 
wanted to beable to start it in one thread, shut it down in another and 
let it execute requests without supervision. :)

Do you know of any issues with omniORB 4.0 and ORBit2 not communicating. 
I couldn't get them to work together. I'm back to ORBit 0.5.15 again in 
my server. :(

What can I do to get you what you need?

I don't know if this is different than before.. I'm not keeping track. 
Sorry.

I notice it compiles with -O2.... I know compiling with optimization can 
produce erroneous results sometimes.

I can get you an account on my machine here if you want to investigate 
this beyond what my level of expertise is. Otherwise I'll help as much 
as I can.
