A program that does that invokes undefined behavior.

You know, you really ought to get your computer fixed so that you can
download your own copy of the standard or access the online copy.
Please read the fifth and fourth paragraphs, respectively, of the
DESCRIPTION sections of the following two pages:

http://www.opengroup.org/onlinepubs/9699919799/functions/pthread_mutex_dest=
roy.html

http://www.opengroup.org/onlinepubs/9699919799/functions/pthread_cond_destr=
oy.html


I don't understand why David makes claims about what the standard says
or doesn't say which are not true.
