I can't really see why either would change. -ggdb does not affect name mangling at all. It just adds debugging information. In any case, changes in symbol or object names should not affect whether the programs runs or not, as long as the changes are consistent. What I was hoping you could see from objdump -d is changes in the instructions. Ian
