+Subject: [PATCH 3/8] Fix array overrun when appending slash to paths
+
+Fix it by extending the array sizes by one character. As the input is
+limited to the maximum path length, there will always be place to append
+the slash. As the php_check_specific_open_basedir() simply uses the
+strings to compare against each other, no new failures related to too
+long paths are introduced.
+We'll let the DOM and XML case handle a potentially too long path in the
+library code.
+
