PCRE functions report errors through
[preg_last_error](https://www.php.net/manual/en/function.preg-last-error.php)/[_msg](https://www.php.net/manual/en/function.preg-last-error-msg.php).
In your case, the latter will tell you "JIT stack limit exhausted".

If this is an actual problem for you, you can adjust the regex to match more at a time, eg. https://3v4l.org/oLkVh will give you about 3x as many numbers, or
you can disable JIT with the
pcre.jit=0 setting.
