When any of these 2 functions are called, I get no output or the output is garbled.
eg (I run this at the end of printable pages, to remove form fields, etc... Get buffer, change it, then print it):

$search = Array(
"|<script[^>]*?>.*?</script>|si",
"|<a href=\"#topo\">.*?</a>|si",
"|<form[^>]*?>.*?</form>|si",
"|<a[^>]*?>|si",
"|</a\s*>|si",
);

$contents = ob_get_contents();	// gets output buffer, empties it and print without forms
ob_clean();
echo preg_replace($search, '', $contents);

In the example I removed some elements from the array and forgot to delete last comma. sorry

I found what is causing it. Setting "ob_gzhandler" as the default output handler in the php.ini or in a script, causes this behaviour.
if "ob_gzhandler" is not used, buffering is fine.

I found the same problem with version 4.2.1 under Linux.

Excuse me... what does bogus mean? Is it my report the bogus one or does it mean that there is really a problem??
I didn't see any answer here, so please, if this was a stupid bug submission, tell me what have I done wrong.

You confirmed correct behavior of ob_gzhandler. Please read the manual on what that does.
