New description:

 Due to circumstances beyond my control, I have a Wordpress site that must
 be installed to a subfolder named "s". I also must use pathinfo type
 permalinks - thus a page with a slug of store-locator would have the url
 /s/index.php/store-locator. Unfortunately this results in a 404, but other
 pages on the site work properly.

 I tracked this down, and what I found is that code in
 class_wp->parse_request is causing this - particularly the code starting
 around line 166ish in version 3.3. The lines in particular that mess
 things up are these three:
 {{{
 $pathinfo = trim($pathinfo, '/');
 $pathinfo = preg_replace("|^$home_path|", '', $pathinfo);
 $pathinfo = trim($pathinfo, '/');
 }}}
 Coming into these lines of code, $pathinfo is /store-locator/, but after
 those three lines of code $pathinfo is tore-locator (the leading s is
 missing). This is because $home_path comes from home_url() which strips
 trailing slashes. The code right before this block further strips
 $home_path down to just the subdirectory portion, which in my case is just
 "s". Then the preg_replace fires and the leading s on the path is lost.

 Temporarily, I added the following line before the three lines above and
 my problems went away:
 {{{
 $home_path .= "/";
 }}}
 Obviously this only works in my particular situation, and I'd like to be
 able to run vanilla Wordpress, but I can't find any combination of
 settings that will preserve my required permalink structure and still
 work. If there's a configuration combination that I'm missing, I'd be very
 happy, otherwise, feel free to contact me if you would like more info or
 if I can help in any way.
