Description:
------------
While using parsekit (latest stable, v1.3.0) in a lint tool to test a larger code 
base I ran into 
"Segmentation fault: 11".

I reduced and reduced and reduced until I ended up with a very small example that 
still caused.

Test script:
---------------
-- test.php
<?php

class Example {
	static $foo = array( T_ABSTRACT, T_PRIVATE );
}

--- parse.php
<?php

$errors = array();
parsekit_compile_file(__DIR__ . '/test.php', $errors, PARSEKIT_SIMPLE);
var_dump($errors);


Expected result:
----------------
-- $ php parse.php
NULL

Actual result:
--------------
-- $ php parse.php
Segmentation fault: 11
