My favorite underutilized approach to debugging is a hybrid of printf/trace debugging and using an interactive debugger. It's great to be able to tap into a running program and just dump variables at a location to a file. For things that are called a lot and very threaded it's great to not have to lock up the program setting and resuming breakpoints, but the flexibility to be able to introduce new logging as you investigate instead of whatever you thought to log is great.
