Yes, I use gdb a lot with C and C++. I find them very useful to step
through some piece of code which is generating a strange value. 

For me they are particularly useful when debugging algorithms that
either involve a lot of mathematics or which has a complex flow.

DrScheme at the moment, which has a debugging function, is still not up
to standard when you have to do this type of debugging. Or at least I
feel in those cases better to fill my code with printfs which would
probably be useless if I had a command line debugger (or if the debugger
was better integrated into DrScheme, even though I would still prefer
the former).

When trying to use DrScheme debug function, values most of the times
print outside the allocated space for it, making it basically useless.
If I can't inspect values, the debugging is useless with the exception
of being able where the code if flowing to.
