I am personally also not using debuggers much -- I think within the two last years it was only the backtrace functionality of gdb twice for a crashing C program :)

I still wonder whether it would make sense to learn more about using them, though. My reasons for not using a debugger often are primarily:

* I work with different kinds of systems. Printf or some equivalent is always available, Debuggers always require a system- and programming-language dependent setup and incur an additional learning curve.

* The hardest bugs I have encountered so far were timing-dependent and could not be reproduced when running under a debugger.

Instead I prefer to work with the printfs and some tools which work non-interactively like strace and valgrind. To me, it makes a lot of sense to look at the code when there is a problem and consider the problem in my mind, although I would not go as far as saying that this is in any way fundamentally superior to stepping through the code interactively?
