Showstopper: ob_start() is b0rked

Did you try to reduce it to a simpler structured example and see if it has
to do with OO, or is it a 100% output buffering issue?

   function transform($buffer) {

 }

 $t = new Test;
 ?>
 foo
outputs 'bar', as it is expected to do, with PHP 4.3.1.

With PHP 4.3.2-RC and PHP 5.0.0-dev it outputs 'foo' which is just
plain wrong.

I reduced it from the XML_Transformer_Driver_OutputBuffer class already
to the code I posted.

I'm not 100% sure but I think a "normal" function works as a callback
for ob_start() -- so maybe it's a OO issue.

Procedural example works as expected. It seems that ob_start(array(object,
method)) is the one causing problems.
