--- Comment #2 from Steve Langasek <steve.langa...@canonical.com> ---
Hello,
The patch for this bug is incomplete. In between the calls to
pipe_barrier_init() and pipe_barrier_destroy() are calls to
pipe_barrier_wait(), which is implemented on top of pthread_barrier_wait().
Since pipe_barrier_init() has not been called, the calls to
pthread_barrier_wait() have undefined behavior, as per
<http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_barrier_wait.html>,
<http://linux.die.net/man/3/pthread_barrier_wait>.
The applied commit is sufficient to fix the immediate SIGFPE problem with
glibc, but the API is still being used incorrectly and could result in future
crashes on other implementations.
