I have been extensively debugging GNAT code (written in Ada95) for 2
years with gdb and found it quite useful. The only awkward thing is
that you have to use the C syntax for expressions but this is
managable...

Vladimir, 
The procedure you are refering to (Get_Prim_Op_Address) is an artifact
that should be invisible to the direct user and will be as soon as
"inter-module inlining" is working: all the Dispatch-Table access
functions will be unconditionnally inlined... The only purpose of this
interface is to make the communication with other OO-Languages
possible as it is done now for C++.
