Bug description: Accessing null string as array in loop causes infinite spooling.

Accessing null string as array in loop causes infinite spooling.

The following code causes php to loop forever. It appears a memory leak unsets the $i variable, although I'm not certain. If allowed to run long enough, error logs appear, such as:
child pid 14467 exit signal Segmentation fault (11)
FATAL: emalloc(): Unable to allocate 1313818981 bytes

<pre>
<?
$myarray = "";
for ($i = 1; $i <= 5; $i++) {
        $v = (isset($myarray[1][$i]['value']))?($myarray[1][$i]['value']):'';
        print $i."...".$v."...\n";
        }
?>
</pre>

Output is as follows
------------
HTTP/1.1 200 OK
Date: Wed, 16 May 2001 22:20:07 GMT
Server: Apache/1.3.19 (Unix) mod_ssl/2.8.3 OpenSSL/0.9.6a
Connection: close
Content-Type: text/html

<pre>
1......
2......
......
......
......
......

------------
After that, it repeats forever...
