The pertinent bit is:

FAIL: test-fchownat (exit: 134)
===============================

test-chown.h:193: assertion failed

Which is a timestamp check:

      ASSERT (st1.st_ctime < st2.st_ctime
              || (st1.st_ctime == st2.st_ctime
                  && get_stat_ctime_ns (&st1) < get_stat_ctime_ns (&st2)));
