Guides

Getting started

  1. 01Your first debugging session: check the build first

Debugging basics

  1. 02Choosing breakpoints that narrow down a bug
  2. 03Step into, Step over, and Step out

Memory and execution

  1. 04Reading registers: PC, SP, and return values
  2. 05Following a failure through the call stack
  3. 06Reading a hex dump: addresses, bytes, and text
  4. 15Why addresses change between runs

Troubleshooting

  1. 07What to check after an access violation
  2. 08Trace a null pointer before adding a check
  3. 09Finding off-by-one errors at array boundaries
  4. 10Use-after-free: readable memory can still be invalid

Build and environment

  1. 11When a variable is optimized out
  2. 12Missing function names and debug symbols
  3. 13Troubleshooting Attach by PID
  4. 14It runs in the terminal but fails in the debugger
  5. 18Undefined reference is a link failure, not a runtime crash

Language errors

  1. 16Reading a Python traceback from the error back to its caller
  2. 17Tracing JavaScript undefined property errors

Investigation methods

  1. 19Reducing a reproduction without removing the bug
  2. 20When to use logs and when to stop at a breakpoint
