Output buffering via ob_gzhandler fails for large pages (more than
4188160 = 1024 * 4090 chars for me). The resulting output is empty
(just headers are sent but no content) - no warning about exceeding
limits or anything else.

To test it I used following code, when I commented out + 1 it worked.

<?
ob_start('ob_gzhandler');
for ($i=0; $i< (1024 * 4090) + 1; $i++) echo '.';
?>

My configuration:

in php.ini I have:
max_execution_time = 30
memory_limit = 8M

PHP 4.2.1
Apache 1.3.26

Same error (probably) reported by someone with PHP 4.2.2 and Apache
2.0.40, see phpMyAdmin bugreport:
