GDB

Purpose

Walk agents through GDB sessions from first launch to advanced workflows: crash diagnosis, reverse debugging, remote debugging, and multi-thread inspection.

Triggers

• "My program segfaults / crashes — how do I debug it?"
• "How do I set a breakpoint on condition X?"
• "How do I inspect memory / variables in GDB?"
• "How do I debug a remote embedded target?"
• "GDB shows ?? frames / no source"
• "How do I replay a bug deterministically?" (record/replay)

Workflow

1. Prerequisite: compile with debug info
