Comment:

 @pikamander2 - Welcome in the trac. Congratulations and thank you for your
 very first ticket.

 I've attached a patched -
 [https://core.trac.wordpress.org/attachment/ticket/47867/47867.diff
 47867.diff] - that should fix your concern. However instead of using `0`
 as length for non-numeric `$num_words` passed to `wp_trim_words()` (e.g. '
 ', 'abc'), I think it's more reasonable to use the default `55` length.

 Also, I didn't apply the fix in `wp_trim_excerpt()` since it's ultimately
 uses `wp_trim_words()`.
