Robert, 

Thanks for the reply. 

I don't even think that the problem has to do with KDevelop. I am nowhere an
expert on KDevelop, but I thought it's only a front-end for GDB while
debugging source code. 
I think the problem has more to do with mismatch between GDB v6.8 and gcc
v4.4.1. 
Do you reckon my assumption is correct? 

Cheers, 

Guray
