It would appear that the stack entry gets laid out the exact same way as the previous call, so pthread_attr_init() sees the previous pthread_attr_t. I added a memset() of att and the issue went away. It looks like that is a good practice anyway.

pthread_attr_t also results in memory leaks on Cygwin.
