Subject: [ruby-core:47620] [ruby-trunk - Bug #7041] Memory leak in Mutex


Issue #7041 has been updated by stass (Stanislav Sedov).


Ruby does not destroy pthread condattr structure after allocating and using it in pthread_thread.c:native_cond_initialize().
This causes a memory leak that can be demonstrated by the following snipplet:

loop do
        Mutex.new
        GC.start
end

The patch attaches fixes this.
The bug happens on both 1.9 and head.
