It seems this bug has been known (but not reported as a bug) since 2010 or
earlier:
http://lists.freebsd.org/pipermail/svn-src-user/2010-November/003668.html
Keep in mind this thread I'm linking has some other complaints about NPTL's
robust mutexes that are orthogonal to this bug report, such as the fact that
you can maliciously mess up other processes that map the same mutex you have
access to. These other complaints are perhaps QoI issues, but not major bugs;
an application has no basis to assume it's safe to let untrusted processes map
its synchronization objects.
