4 last bytes are "\x20\x20\x20\x20"
Here i've used 'plain' client that cannot affect traffic. Maybe this IS apache bug?

There's nothing wrong with pack, neither CGI nor apache. I guess your client can't
handle this.
You can verify this youself with:
<?
$foo = pack('L', 0);
$f = fopen('/tmp/pack', 'wb');
fwrite($f, $foo);
fclose($f);
?>
$ hexdump /tmp/pack
0000000 0000 0000
0000004
As you can see, it's perfectly valid (tested with apache, mod_php).

I've just compiled CGI version, it works fine, output is "\x00\x00\x00\x00".
Also here's my configure string from phpinfo:
'./configure' '--with-apxs=/www/bin/apxs' '--with-mod_charset' '--without-pear'
'--with-zlib' '--with-bz2' '--with-mysql=/usr' '--disable-xml'
make CFLAGS="-DHAVE_MYSQL_MYSQL_H -I/www/include"

<?= pack("L",0); ?>
On PHP 4.1.0, compiled as Apache shared module outputs string "\x20\x20\x20\x20" (4
spaces). It is not "L"-specific issue. <?= pack("C",0); ?> also outputs "\x20".
Any non-zero values are processed OK.
PHP 4.0.1pl2 and 4.0.6 seems to work correctly.
Configuration includes --with-apxs, --with-mysql (bundled), --with-bz2, --without-xml
and --without-pear.
