According to phpinfo(), I have the following values:

     output_handler (no value)
     zlib.output_compression Off
     zlib.output_handler (no value)

The weird thing is, I have changed nothing in php.ini, yet PHP 5.3.22  
fails, but PHP 5.4.12 works.

I have to admit that I may be comparing apples with oranges here. The  
versions of PHP 5.3 (5.3.15 and 5.3.22) I was using so far came from a  
different repository than PHP 5.4.12, so there is a chance that they  
were built with different options.
