Addendum: It is not a problem with wrong extension dir in php.ini
(because all extensions are linked static) like in other bugs.
The configuration phpinfo() can be found at:

Description:
------------
The following error occurs sometimes on the ext/standard function
get_browser():
[20/Oct/2003:08:54:59] info (13034): for host
p5084725C.dip.t-dialin.net trying to GET /index.php, php4_execute
reports: PHP Fatal error: Nesting level too deep - recursive
dependency? in /pangaea/htdocs/www.pangaea.de/index.php on line 28
Line 28 contains the call to get_browser(). All other PHP functions do
not fail. In other scripts which use get_browser() the error also
occurs.
The problem is: You cannot reproduce it, because it happens only on
heavy server load and when it happens the first time it does not go
away until server restart.
PHP runs on SunONE with NSAPI, so compiled with ZTS.
I would debug the code and fix the error; but my problem is that I do
not know WHERE in get_browser the error occurs.

Reproduce code:
---------------
<?php
// look if referer comes from google and extract search query
//
http://www.google.de/search?sourceid=navclient&hl=de&q=%22age%2C+error%22+pangaea
//
http://www.google.de/search?q=%22age,+error%22+pangaea&hl=de&lr=&ie=UTF-8&filter=0
if (isset($_GET['query'])) {
$query=$_GET['query'];
} else {
if (isset($_SERVER['HTTP_REFERER']) &&
preg_match('/^http:\/\/.*?google\..*?\/search\?(.*?)$/i',
$_SERVER['HTTP_REFERER'], $matches)) {
$a = split ('&', $matches[1]);
for ($i=0; $i<count($a); $i++) {
$b = split ('=', $a[$i]);
$name=urldecode ($b[0]);
$value=urldecode ($b[1]);
switch ($name) {
case 'q':
$query=$value;
break;
case 'ie':
$encoding=$value;
break;
}
}
}
if (isset($query) && isset($encoding))
$query=mb_convert_encoding($query, "ISO-8859-1", $encoding);
}
// detect browser
$browser=get_browser();
// if not crawler redirect user to homepage (do not forget to
transmit query because referer can get invalid after redirect)
if ((!$browser->crawler) && isset($_SERVER['PATH_INFO'])) {
if (isset($query)) {
header("Location:
http://".$_SERVER['HTTP_HOST']."/?query=".urlencode($query));
} else {
header("Location: http://".$_SERVER['HTTP_HOST']."/");
}
exit();
}
// if a crawler like google is visiting: prepare keyword list to
display and extract page number
if ($browser->crawler) {
$page=0;
if (isset($_SERVER['PATH_INFO'])) {
if (preg_match('/^\/(.*?)\.html$/', $_SERVER['PATH_INFO'],
$matches)) {
$page=$matches[1];
} else {
header("HTTP/1.0 404 Not Found");
exit();
}
}
$lines=file("../globals/googlelist.txt");
if ($page*1000>=count($lines)) {
header("HTTP/1.0 404 Not Found");
exit();
}
}
?>
