There are those, but there are others, most of which are so obvious[1]
we're not mentioning them, assuming you're familiar with them too. I
usually eschew debuggers as well, but I'm beginning to suspect that you've
spent so much of your programming life immersed in the kernel that you
haven't used a debugger enough to know what sorts of things it's actually
good for. Not all the world's a nail, but there are times when the bigger
hammer approach is the right one.

One of these days you should give revision control a try too. Not to
mention bug tracking. :P

[1] eg I've found many a compiler bug in 5 minutes of single stepping that
days of eyeballing source and adding printfs failed to discover.
