Re: [std-proposals] std::thread::detach() can segfault

Sorry for the confusion but I'm not using pthread_create directly but std::thread() does. All the C++ thread calls use the underlying pthread library.

You're right, it's supposed to throw an exception. So the problem is in
the pthread library in the pthread_detach() call itself more specifically.

You see, under high concurrency I'm creating simple threads followed
immediately by detach(). And very rarely that call crashes.

I'm really surprised it crashes given I assumed libpthread was the most
tested library of all time.

Are you checking whether the pthread_create call succeeded?
