Use some random URL parameter and detect it in your script. When
detected enabled display errors:
<?php
if( isset( $_GET['knjdcrksjhfcsjkhfndkf'] ) )
{
ini_set( 'display_errors', 1 );
}
?>
Then see if you get any errors. Although, if you're seg faulting, you
still won't see an error since the program just dies.
Cheers,
Rob.
