Comment:

 On my quite standard installation (wp in subdirectory,nginx) : this bug
 occurs on **every** page.


 {{{
 $home : https://<mysite.com>
 $siteurl : https://<mysite.com>/wp
 $wp_path_rel_to_home : /wp
 $_SERVER['SCRIPT_FILENAME'] : /www/<myusername>/public/index.php
 }}}

 :
 so on line 113,

 {{{
  $pos = strripos( str_replace( '\\', '/', $_SERVER['SCRIPT_FILENAME'] ),
 trailingslashit( $wp_path_rel_to_home ) );
 }}}
 will always return 0, relative path is NOT in server script filename

 --> home_path will always return "/"

 --> generating tons of open_basedir restriction in effect, as **wordpress
 tries to read the root of the server** on includes/misc.php on lines
 278/279 !

 I had to manually patch wp core to fix it , which will break on every
 update ..
