New Comment:
Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader. These extensions often modify engine
behavior which is not related to PHP itself.
rename_function() is part of apd and was made to help you debugging
stuff, PHP isn't made for such tricks so they can break from time to
time.

Description:
------------
I'm using some functions like: function_exists, rename_function, eval
and custom function for set_handler_error.
I tested on PHP 5.3(snap) and it still crashing.
Reproduce code:
---------------
something like that:
foreach ($opt_cache_func as $func => $func_hook) {
if (function_exists($func) && rename_function($func,'org_'.$func)) {
if (empty($func_hook) || !is_string($func_hook)) $func_hook =
$def_func;
print 'dupa'; exit;
$declaration = sprintf('function %s(%s) {%s}',$func,'',"return
$func_hook(func_get_args(),'org_'.'$func');");
eval($declaration);
}
}
Expected result:
----------------
Should not crashing:)
Actual result:
--------------
