#### TECHNICAL PAPER

# DEBUGGING MULTITHREADED CODEBASES AT SCALE

Finding race conditions in concurrent code using just-in-time binary instrumentation, fuzzing, and time travel

# What’s inside

Multithreaded application architectures help improve performance; but they also increase the risk of concurrency issues such as deadlocks or race conditions. And these can be non-trivial to reproduce...

This technical paper reveals technologies and techniques for easily diagnosing the root cause of multithreading issues and finding race conditions before your customers do:

- **Time travel debugging** - making bugs 100% reproducible, every time.
- **Thread fuzzing** - exposing concurrency issues during testing by interfering with the regular scheduling of C++ threads.
- **Multiprocess correlation** - debugging shared memory corruption more easily.
