OnUpdateRfc1867Freq used ZEND_ATOL(), which silently truncates trailing garbage (e.g. "5 apples" becomes 5), the same parsing bug recently fixed for session.cookie_lifetime. Switch to is_numeric_string_ex() to validate the numeric portion strictly, still allowing the optional trailing "%" for percentage mode.
Covers the "%"-suffixed form of session.upload_progress.freq, alongside the plain-integer case added in rfc1867_invalid_settings_3.phpt.

What happens with trailing spaces? Not sure how our INI parser deals with those.
