I assume the code in another_thread attempts to obtain the size of the
current thread. But the code just reads back the default stack size,
which may have changed due to the set_default_thread_stack_size call.
One way to obtain the size of the current thread stack is this call:
if(int err = ::pthread_getattr_np(pthread_self(), &attr))
throw std::system_error(err, std::system_category(),
"pthread_getattr_np");
This should give consistent results all the time.
