How would you use that for debugging?
(Sry I'm too cheap to go and buy the book)
My best guess is that in some configurations it raises SIGSEGV and then dumps core. Then, you use a debugger to analyse the core dump. But then again you could also set a breakpoint, or if you absolutely want a core dump, use abort() and configure SIGABRT to produce a core dump.
to see whether your code has executed a certain path (like printf("here") but as a crash)
