I'm using EL6 with all updates applied and getting bit by a PHP5 bug that was fixed a year and a half ago...

https://bugs.php.net/bug.php?id=52534

EL6 ships with php 5.3.3, which was released prior to the bug fix. What are the chances that this fixed bug can be reported/fixed upstream at the prominent North American Linux Vendor? Here's sample code that demonstrates the problem:

function CheckBug52534(){ $check = array(1 => 'a', -1 => 'b'); $str = var_export($check, true); $str = "$a=$str;"; eval($str); if (!isset($a[-1])) return true; }

echo (Checkbug52534()) ? "has it" : 'not found';
