IME, yes. It isn't as easy as with -O0 or -O2, particularly because sometimes the backtraces "don't make sense" (a function call is elided) or (as with -O2) a variable's lifetime has gotten shorter, but it is still possible. In particular, a backtrace will generally still tell you what library/program to -O0 so that you can bring the full power of gdb to bear. Because gdb (et al) is still able to match the function addresses on the stack with the -g3 generated symbols. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
