     * This routine comes nowhere close to out-of-memory (uses 45MB).
     * Yet it goes out of memory in PhpUnit 10 (uses 2GB!).
     * Works fine in PhpUnit9-.
     * We can mitigate the problem by changing entirely-null rows
     * to empty rows in rangeToArrayYieldRows. (uses 455MB).
     * That's a breaking change, but might be worth considering.
     *
     * Aha! I have narrowed the problem to self::assertCount,
     * which has a ready substitution. I will report the problem
     * to Phpunit if I can come up with a simpler example.
