The following script :

  <?php echo abs("-1");?>

leaks 3 bytes and produces no output:

  Content-Type: text/html

  zend-scanner.l(1163) :  Freeing 0x082307E0 (3 bytes)


This script :

  <?echo abs("-1.5");?>

leaks 5 bytes and produces no output:

  Content-Type: text/html

  zend-scanner.l(1163) :  Freeing 0x082307E0 (5 bytes)


while this one :

  <?php echo abs(-1.5); ?> 

does not leak and produces output :

  Content-Type: text/html

  1.5
