Comment (by leavengood):
As far as style of your latest patch, it isn't quite right. The space goes
after the if but before the parenthesis, see the line right above your
added one.
As for the substance of the patch, it seems from Ingo that a detached
thread passed in to pthread_join may no longer be valid, so I'm surprised
that it works to check for the flags. In your tests that may only work
because the memory used for the thread has not yet been written over, but
that is certainly not always going to be the case. The fact that the free
throws an error without your patch does point to this being the case.
