Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

this is due to now:

substr("", 0) will return "" instead of false: http://php.net/manual/en/function.substr.php

I have create an issue in phpsass, hope they will fix it soon, thanks

Description:
------------
memory limit exhausted when using win 10 with PHP 7.0.1 VC14 x64 Thread Safe (2015-Dec-17 00:17:17)

no matter how high I set my memory limit, it will get exhausted, and it only happen when running the php scss parser from richthegeek, sample code provided below.

memory limit I have tried: 128MB, 256MB, 512MB

this does not happen in PHP 5.6 VC11 x64 Thread Safe (2015-Nov-26 04:33:59)
with memory limit 128MB and other supported settings the same (obviously excluding mysql extension)

changes to php.ini:
include_path = ".;S:\php\PEAR"
memory_limit = 512MB

Test script:
---------------
this error only happen when using scss parser from richthegeek
https://github.com/richthegeek/phpsass

require 'SassParser.php';

$options = array(
	'style' => 'nested',
	'cache' => false,
	'syntax' => 'scss',
	'debug' => false,
);

$parser = new SassParser($options);
$css = $parser->toCss($some_big_scss_file);
//note my scss file have around 1000 lines

Expected result:
----------------
scss code should be successfully parsed regardless if there is error in the scss (as like the behavior in php 5.6)

Actual result:
--------------
php stopped the execution with memory limit exhausted

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 134217736 bytes) in some_path\libraries\script\SassScriptLexer.php on line 118
A PHP Error was encountered

Severity: Error

Message: Allowed memory size of 536870912 bytes exhausted (tried to allocate 134217736 bytes)

Filename: script/SassScriptLexer.php

Line Number: 118
