--- Additional comment from Petr Pisar on 2018-08-23 07:06:09 GMT ---
The threads support is known to be broken and there is no fix in sight. I
recommend disabling these thread tests that are actually optional and run
explicitly when building RPM package in contrast to upstream the does not run
them (for the threads support immaturity).

Reproducer:
$ while (THREAD_TEST=1 prove -b t/90threads.t); do :;done
