"worker 1 processed some too" subtest of t/08-refcounter.t fails sometimes.
This is a subtle problem certainly not in the test. I was able to get corrupted memory handling aborts and other nasty reports when narrowing this issue. Provided nothing uses perl(threads::tbb*) in Fedora and upstream has not been able to fix in in last three years, I will retire this package.
Blocking in koji requested <https://fedorahosted.org/rel-eng/ticket/5908>.
Package has been removed from Fedora 21.
