Bug description:Crash when calling call_user_func with unknown function name
Description:
------------
Firstly the function is_callable(array('B', 'noSuchMethod')) returns true
even
such static method does not exist. This could be caused by class A having
magic
method __call (which shouldn't accept static methods though).
Still because of this the code fails with segmentation fault.
Test script:
---------------
class A
{
public function __call($method, $args)
{
if (stripos($method, 'get') === 0) {
return $this->get();
}
throw new BadMethodCallException("No such method");
}
protected function get()
{
$class = get_class($this);
$call = array($class, 'noSuchMethod');
if (is_callable($call)) {
call_user_func($call);
}
}
}
class B extends A {}
$input = new B();
echo $input->getEmail();
Expected result:
----------------
Script should end with no output.
Actual result:
--------------
Segmentation fault.
