Hi @AlexanderBarnt and thanks for opening this issue!

1. Just to be clear, is the file you are compiling, main.cpp, identical to the file BS_thread_pool_test.cpp from this repository? If the code for your main.cpp is different, please post it here.
2. Please run the PowerShell script BS_thread_pool_test.ps1, which will compile the test program with MSVC compiler flags that I know for certain work. Let me know if that works or not. If not, then the problem is probably in one of the extra compiler flags you are using, so please try removing some of them and seeing if that works.
