Description:
------------
Latest php snap of 5.0
Apache 2 filter
mb_string, gd, mssql, and mysql only dll's loaded
Error handler class - constructor calls set_error_handler and works just fine, descructor calls restore_error_handler and the server crashes nicely - not only the phpdll but all of apache as well in a second message. I have some dump files if you need them, just leave a message.
Reproduce code:
---------------
<?php
class Error
{
function __construct()
{
set_error_handler(array(&$this, 'handler'));
}
function __destruct()
{
restore_error_handler();
}
function handler($no, $str, $file, $line, $ctx)
{
echo '<pre>';
echo 'no : ' . $no . "\n";
echo 'str : ' . $str . "\n";
echo 'file : ' . $file . "\n";
echo 'line : ' . $line . "\n";
echo 'ctx : ';
print_r($ctx);
echo '</pre>';
}
}
$error = new error();
echo $dog;
?>
Expected result:
----------------
no : 8
str : Undefined variable: dog
file : ****/test.php
line : 29
ctx : Array
(
[GLOBALS] => Array
*RECURSION*
[_POST] => Array
(
)
[_GET] => Array
(
)
[_COOKIE] => Array
(
)
[_FILES] => Array
(
)
[error] => error Object
(
)
)
Actual result:
--------------
Comment out the restore_error_handler and it works jim dandy
