I get this output (run in linux, using cli):

/www/apache-1.3.27/htdocs/t.php on line 13

if its of any use, the winxp error signature:
szAppName : php.exe
szAppVer : 4.3.2.2
szModName : php4ts.dll
szModVer : 4.3.2.2
offset : 000ae419

this code causes a crash for me:
$urls[]="http://www.stichtingoikos.nl/";
$urls[]="http://www.wereldburgers.nl/";
$urls[]="http://www.stichtingoikos.nl/";
$urls[]="http://www.wereldburgers.nl/";
$urls[]="http://www.wereldburgers.nl/";
foreach($urls as $url) {
$fp = fopen($url,"r");
if($fp) fclose($fp);
}
notes:
1) it does not crash if i omit "if($fp) fclose($fp);"
2) the size of the url list needed for a crash could vary. for example,
while above hosts resolve to the same IP, it also crashes for a list
using different IPs; such a list for me had to be a couple of entries
larger to crash.
3) i get a winxp "PHP Script Interpreter" crash dialog on the above
code, though when working with bigger lists i occiasionally only got an
Apache Internal Server error and no crash dialog
i tested this on 4.3.1 and 4.3.2-RC (2003-04-25)
