Comment:

 Confirmed, also on older installs.

 With a non-numerical slug the matched query is
 `category_name=parent%2Fchild&name=test&page=`, whereas with a numerical
 slug it is `category_name=parent&name=child&page=12345`.

 The rewrite rule for the `/%category%/%postname%/` structure is
 `(.+?)/([^/]+)(?:/([0-9]+))?/?$`
 (`category_name=$matches[1]&name=$matches[2]&page=$matches[3]`).

 Looks like numerical slugs should be forbidden in that case and suffixed
 (e.g. `1234-2`). @boonebgorges didn't you fix something similar recently?
 Can't find the ticket.
