Become a GDB Power User
summary
Demos show concrete GDB tricks: use TUI mode for side-by-side source/disassembly, load Python scripts to build pretty-printers and automatic handlers, and attach hooks to events. Reversible debugging records every instruction (observed up to ~50,000× slowdown) so reverse-continue and a hardware watchpoint find an out‑of‑bounds write (index 33 into a 32 element array). Also covered: dynamic printf without editing code, fork/multi‑process follow modes, and saved command history.
