PHP Error clashes with ob_gzhandler

[Boldewyn]

I have a PHP file starting with

ob_start('ob_gzhandler');

Placing errors below this line leads to garbage output, i.e., gzipped content without the Content-Encoding header. Throwing an error above works as advertised.

I'm using PHP 5.4.4.

How are you linking in PHP Error? Are you loading it in PHP after the call to ob_start, or are you loading it through php.ini?

[Boldewyn]

I'm loading it via php.ini with

php_error.autorun = On

i.e., beforehand. I'll try loading afterwards, as soon as I get to my dev machine again.
