Description:
------------
opcache seems to 'cache' the return value of a require statement, even if
opcache_invalidate or opcache_reset is called. A test script which returns a closure is written to
disk, required and result method is called. File is overwritten and called again. Output should
differ, but is the same. A helper var written to the same file IS correctly updated.

Result is wrong most of the times.

php -d zend_extension=/usr/lib/php/modules/opcache.so -d opcache.enabled=1 -d opcache.enable_cli=1
-d opcache.optimization_level=0xffffffff public_html/php/opcache.php

opcache.optimization_level=0x00000000 also fails.

Test script:
---------------
<?php

$tmp = tempnam(sys_get_temp_dir(), 'test');

file_put_contents($tmp, '<?php $s = ' . microtime(true) . ';return function(){
return "a";};');

$f = require $tmp;
var_dump($s, $f());

sleep(2);
file_put_contents($tmp, '<?php $s = ' . microtime(true) . ';return function(){
return "ab";};');

opcache_invalidate($tmp, true);
$f = require $tmp;

var_dump($s, $f());
unset($f);
opcache_reset();

$f = require $tmp;
var_dump($s, $f());


Expected result:
----------------
double(1381930079.4517)
string(1) "a"
double(1381930079.452)
string(2) "ab"
double(1381930079.452)
string(2) "ab"


Actual result:
--------------
double(1381930079.4517)
string(1) "a"
double(1381930079.452)
string(1) "a"
double(1381930079.452)
string(1) "a"
