FWIW, I almost always use valgrind before a debugger, when tracking down segfaults. It doesn't catch everything, but 90% of the time, it gets me to the right region of code in a single run.
Good good, just wanted to advocate for my favorite tool there. But, in my experience, segfaults are usually the easiest bugs to resolve. Unlike a sign error in my math, they're impossible to miss!
That said, tooling to get rid of them entirely is not to be sneezed at :)
