Function pathinfo() crashes on simple call. 
For example <? pathinfo("/dsds.asa") ?> gives segfault.

Following little fix wont crash anymore:

# diff ext/standard/string.c.old ext/standard/string.c
1271d1270
<               int ret_len;


And a backtrace:
Starting program: /root/php5/sapi/cli/php /data/docroot/test.php

Program received signal SIGSEGV, Segmentation fault.
