Description:
------------
Using the syntax given below leads to a temp file left in tmp directory.
The file is file.gz with random name like php??????
Previous version 5.2.1 seems to be OK.

fopen('compress.zlib://http://www.somedomain.pl/file.gz', 'rb');

Reproduce code:
---------------
$f = fopen('compress.zlib://http://www.somedomain.pl/file.gz', 'rb');
if ( !$f ) die("Error");
while ( !feof($f) ) {
echo fread($f, 1024);
}
fclose($f);

Expected result:
----------------
There shouldn't be any file left in the tmp directory.
