Good ol’ Daniel LeCheminant has a solid answer on what a data breakpoint does, so i’ll toss in some anecdotes that highlight useful uses: Any scenario where you know what will change, but have little or no idea where the code changing it lives (since otherwise you could simply use a conditional breakpoint). Specifically, “Impossible” … Read more
You should take a look at the command command, which enables you to add gdb commands as a breakpoint is hit. See the breakpoint command list section of the gdb manual. For example: break someFunction commands print var1 end will, when the breakpoint on someFunction is hit, automatically print var1.

Update: There is now a better answer to this question: use GDB _is_caller convenience function. The need you describe comes up quite often, usually in the context of some_utility_fn being called a lot, but you only are interested in the call which comes from some_other_fn. You could probably script this entire interaction using the new … Read more
