CI causes Apache to drop an empty connection/response

EDIT 2: False alarm, all that was needed was a recompile of PHP.

I was running CI 1.7.2 on my local development platform (pre-installed apache that comes with Snow Leopard), no problems here.

Later I uploaded the project to a live server and changed the settings in the config files to match the database etc.

When I later accessed the site it wouldn't give me any response thru CI's index.php (not using any .htaccess/rewrite stuff). I created a phpinfo test page in the same directory and it worked fine.

I don't get any visible error, the apache error log doesn't give me anything useful either.

I started to track down where the problem starts;

/system/codeigniter/CodeIgniter.php around line 200, I found the following lines

Code:

// Mark a start point so we can benchmark the controller
$BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_start');

$CI = new $class();

If I put;

Code:

echo "test"; die;

On the line in the middle of $BM and $CI, I see the "test" output when accessing the site, although if I put it after the line with the $CI variable, it will load for a couple of seconds and then send me an empty response.

Anyone have a clue of what it could be?
