Additional info:
Comment 1 Florian Weimer 2016-02-09 19:01:19 UTC 
This is consistent with calling pthread_barrier_destroy on a barrier which has not been initialized with pthread_barrier_init.  This is likely an application bug.  (The current glibc implementation does not update the count member after initialization.)
Comment 2 Jan Kurik 2016-02-24 14:27:09 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.
