PHP Bug Type: Reproducible crash
Bug description: crash in recursive call of __call
Description:
------------
This ill-behaved code crashes php. I know one should never write things
like this, but this sample is an oversimplified version of a much bigger
code I'm working with, and I've just spot my error after trying to
simplify the code to attach here. PHP should emmit a warning when such
things happen, as with __set and __get, saying that $this->func() isn't
defined, when called inside a __call handler.
Reproduce code:
---------------
<?
class test
{
function __call($func, $args)
{
$this->hello();
}
}
$a = new test;
$a->hello();
echo "You won't read this";
?>
Expected result:
----------------
A warning saying that $this->hello isn't defined.
Actual result:
--------------
The coredump is a bunch of
#0 0x0821d843 in zend_call_function ()
#1 0x0821e76a in call_user_function_ex ()
#2 0x0823cfa5 in zend_std_call_user_call ()
#3 0x0825f8ee in zend_do_fcall_common_helper ()
#4 0x0825faf1 in zend_do_fcall_by_name_handler ()
#5 0x0824daf8 in execute ()
repeated over and over
