Actually, it sounds like a random failure. On a different system (which
excludes broken hardware), I ran:
ok=0; fail=0; while true ; do if make check; then ok=$(($ok+1)); else fail=$(($fail+1)); fi; echo "TESTS: $ok / $fail"; done &> log

After some time:
TESTS: 45 / 5

And the "stride" test was always the one failing.

Would be interesting to know if this is a liboil bug or a test bug.

Running the stride test only:
for i in $(seq 1 1000); do ./stride  | md5sum; done 2>/dev/null | uniq -c

So it always fail several times in a row. (16 or 17 times)
