Hmm, you are removing an (appearant) abstraction that I didn't know was there but remember to have asked for in the thread for dumping a late callgraph for Ada purposes. Is the abstraction not working or was it simply a hassle to keep the VCG path working (I don't thjnk I have ever seen a VCG consumer ... ;)). Btw, I of course have my own CFG dumper (producing graphviz input) in my local tree - attached for reference (I'm simply using it from gdb sessions). Richard. > Ciao! > Steven
