Race conditions and other issues with multi-threaded code can be fiendishly difficult to debug. Too often we rely on printf, coffee and swearing -- we can do better!

A practical talk with lots of demos and few slides, covering topics including:

• How to debug multiple threads in GDB
• How to use ThreadSanitizer (TSan) to easily debug race conditions
• How to use Helgrind for detecting thread synchronization errors
• How to use time travel debugging to quickly root cause bugs
• How to use thread fuzzing to expose concurrency bugs
