threadpool is FUBAR because jK added a lock-free queue to it that can only work in an SPSC context: 1) threads will never push two tasks with the same id, but can overwrite still-running tasks (!) mapping to the same index 2) threads can also concurrently write to the same index if task A has id K and task B has id K+ringSize 3) other issues I didn't delve into for now, just disable it via https://github.com/spring/spring/blob/develop/CMakeLists.txt#L363 |
