Description:
------------
Octal escape sequences in double quotes or backticks are not checked for overflow.

Test script:
---------------
<?php
echo ord("\777"[0]) . PHP_EOL;
echo ord("\666"[0]) . PHP_EOL;
echo ord("\555"[0]) . PHP_EOL;

Expected result:
----------------
Some kind of error, because all of \777, \666, \555 sequences are invalid, their value is greater
than 255.

Actual result:
--------------
255
182
109
