Description:
------------
If you try to include a file that contains "${}" (empty variable in a double quote d string), php crash on the include instruction, no log is generated.

I'd expect a parse error pointing the faulty code.

Test script:
---------------
fileA : 
include "fileB.php";

-------------------------
fileB : 
$test = "test ${}";

Me neither. Both PHP 5.6.18 and PHP 7.0.6 (on Windows) report a
parse error.

To the OP: please mention the exact PHP version and the OS on
which this behavior occurred. Also double-check that
error_reporting & friends are appropriately configured.
