Bug description: PHP segfaults when assigning $errcontext to Smarty var when
debugging enabled
Description:
------------
When $smarty->debugging = true and using $smarty->assign
to assign a template variable with the value of
$errcontext, PHP segfaults when trying to output the
debugging console for Smarty.
Reproduce code:
---------------
<?
include('Smarty.class.php');
$smarty = new Smarty();
$smarty->debugging = true; // the error will not occur if
debugging = false
set_error_handler("error_handler",E_ALL);
function error_handler($errno, $errstr, $errfile, $errline,
$errcontext)
{
global $smarty;
$smarty->assign('killme',$errcontext);
$smarty->display('killsmarty.tpl'); // this file can be
empty but it has to exist
echo($errstr);
}
trigger_error("Uh-ho!",E_USER_ERROR);
?>
Expected result:
----------------
$errcontext should be assigned to Smarty template variable
$killme.
Actual result:
--------------
