please read carefully. this crashes PHP. (i.e. PHP.exe causes a GPF) 

the code is:
<?php
function ImageExists($url) {
  $r=@getimagesize($url);
  return $r[2]!=0;
}
echo ImageExists('http://domain/dir1/dir2/dir3/image.gif');
?>

make sure the path:
http://domain/dir1/dir2/dir3/
containts THREE directories after the domain (i.e. 6 forward-slashes total), and that the PATH physically EXISTS.

AND make sure that the file (in code 'image.gif') DOES NOT exist.

You can test against:
http://economads.com/libaware/_font/title/image.gif

This crashes on my server - running PHP 4.3.0 as CGI with IIS Win2000. 

Hope this helps.

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.

Thank you for your interest in PHP.

don\'t submit two reports about same issue..

sorry - i wasn't sure, since the last report was changed to 'bogus' if it's already part of history and also the new summary field is more exact. i will follow with comments with previous report (21479)
