This blog will not discuss the pros and cons of User Space Thread, nevertheless, you might want to check this. I believe that knowing the machinery of User Space Thread implementation will help us to understand the new Coroutine feature released in C++20 (Talk from cppcon 2015). [Read More]

The following program will cause core dump. /* gcc version 10.0.1 20200314 (experimental) (GCC) Ubuntu 18.04.5 LTS x86_64 GNU/Linux 5.6.2 */ #include <thread> #include <iostream> int main() { std::thread t{[]() { std::cout <<"Hello from thread t"<<std::endl; }}; } The reason for the core dump is std::terminate() called by the destructor of the std::thread object t. // from std::thread header ~thread() { if (joinable()) std::terminate(); } The default terminate handler calls abort.
