Overview
What this challenge is about.
Read the 8k-line allocator + order-pool code (provided), plus 3 production crash dumps and 14 hours of pre-crash telemetry. Hypothesize root cause (likely candidates: use-after-free in cancel/replace path, double-free under race, buffer-overrun in the variable-length order tag). Build a deterministic reproducer under AddressSanitizer + ThreadSanitizer using a recorded market-replay feed. Propose a fix that does not add allocations on the hot path. Deliver: root-cause memo (3-5 pages), reproducer test (added to test suite), fix as a pull request with latency benchmark before/after.
The Brief
What you'll do, and what you'll demonstrate.
Find and fix a heap-corruption bug in a low-latency C++ order gateway without regressing the 18-microsecond median latency budget.
Earning criteria — what you'll demonstrate
- Read crash dumps and reason backward to memory-corruption root cause
- Use ASan + TSan to build deterministic reproducers from non-deterministic bugs
- Fix memory-corruption bugs without violating latency budgets
- Communicate systems-debugging findings to non-systems engineers
