Re: Thread: memory leak when using not detached thread?

[Anrdas Vass]

Yes, but SIGSEGV remains....
A backtrace shows that calling pthread_detach() quickly after
pthread_create() /quickly means less than 10 ms/ dumps core in certain
cases. (glibc-2.2.5)
This small patch seems to help if detach() is called instead of start(). I
don't know what would be the Right Thing (tm) to do, if someone wants to
call detach() to detach a joinable thread.
Perhaps an ost::Thread::sleep(10) call before pthread_detach()?
