If you change the test trait to

<?php
trait test {
 function tester($cCookie) { 
  if ($cCookie) {
   if (isset($_COOKIE[$cCookie])) {
    return $_COOKIE[$cCookie];
   }
  }
  return false;
 }
}

//
you get a zend_mm_corrupt

Description:
------------
if you use GLOBAL variables inside traits, e.g. $_COOKIE, it segfaults

Test script:
---------------
<?php
trait test {
 function tester($cCookie = false) { 
  if ($cCookie) {
   if (isset($_COOKIE[$cCookie])) {
    return $_COOKIE[$cCookie];
   }
  }
  return false;
 }
}

<?php
class asda {
 use test;
 function beep() {
  $this->tester("test");
 }
}

$a = new asda();
echo $a->beep();

Expected result:
----------------
false, or contents

Actual result:
--------------
Segfault


------------------------------------------------------------------------
