CPUThreadPoolExecutor::threadRun crash

[KingOX-cpp]

HI, i use CPUThreadPoolExecutor to run my code but i don't known what's the reason of the crash infomation,
The crash stack is shown in the following two images.
There is no other extra information about my own code in the stack.
Ubuntu20.04+GCC 11.4

[KingOX-cpp]

My setting like this will definitely crash
sequenced_worker_pool_ = std::make_sharedfolly::CPUThreadPoolExecutor(thread_nums_));

otherwise,set min thread nums. it works,all fine.
sequenced_worker_pool_ = std::make_sharedfolly::CPUThreadPoolExecutor(std::make_pair(thread_nums_, thread_nums_));

So, this crash occurs when reducing the number of threads？

How to avoid the reducing crash?
