Potential zero threads

[TLCFEM]

thread-pool/BS_thread_pool.hpp

Line 100 in 9d43f5d

explicit thread_pool(const concurrency_t thread_count_ = std::thread::hardware_concurrency()) : thread_count(thread_count_ ? thread_count_ : std::thread::hardware_concurrency()), threads(std::make_unique<std::thread[]>(thread_count_ ? thread_count_ : std::thread::hardware_concurrency()))

std::thread::hardware_concurrency() may return 0. So when constructed as thread_pool(), thread_count may be initialised to 0. thread_count(thread_count_ > 1 ? thread_count_ : 1 may be safer.

Thanks, I will fix this in the next release.
