Description:
------------
After installing php 5.2.6 and executing its phpt's, the following tests failed:
 ext/bz2/tests/bz2_filter_compress.phpt
 ext/bz2/tests/bz2_filter_decompress.phpt

bz2 extension is loaded and phpinfo() displayes:
Stream Filter support -	bzip2.decompress, bzip2.compress

However, the section of registered stream filters doesn't contain bzip2.compress/decompress


Reproduce code:
---------------
<?php
$streamlist = stream_get_filters();
var_dump($streamlist);
?>

Expected result:
----------------
array(9) { [0]=>  string(12) "string.rot13" [1]=>  string(14) "string.toupper" [2]=>  string(14) "string.tolower" [3]=>  string(17) "string.strip_tags" [4]=>  string(9) "convert.*" [5]=>  string(8) "consumed" [6]=>  string(6) "zlib.*" [7]=>  string(7) "bzip2.*" [8]=>  string(15) "convert.iconv.*" } 

Actual result:
--------------
array(7) { [0]=>  string(12) "string.rot13" [1]=>  string(14) "string.toupper" [2]=>  string(14) "string.tolower" [3]=>  string(17) "string.strip_tags" [4]=>  string(9) "convert.*" [5]=>  string(8) "consumed" [6]=>  string(6) "zlib.*" }
