 Severity:  normal          |   Keywords:  has-patch

 Background: #25061

 [17592] added a fix to `_unzip_file_pclzip()` for `mbstring.func_overload`
 (see #15789).

 However, it does not check that the value of `mbstring.func_overload`
 actually redefines string functions and not `mail()` or regex functions.
 See `POMO_Reader()` for the correct check: [source:tags/3.6/wp-
 includes/pomo/streams.php#L17].
