Give me 15 minutes & I'll change your view of GDB
summary
Demos of GDB show three concrete workflows: use TUI mode (Ctrl‑X, Ctrl‑L, Ctrl‑P) to get source, asm and registers in curses windows; use the Python API to inspect and create breakpoint objects and pretty‑printers; and use reversible debugging plus a watchpoint (recording, reverse‑continue, reverse‑step) to find who wrote a bogus return address. The reversible run reproduces an intermittent crash, reveals an overwrite from index 35 into a 32‑element array (sizeof vs element count), and pinpoints the faulty write.
