Description:
------------
Calling a method on a non-object results in a non catchable fatal error, that cannot be handled by an error_handler. It would be great if it would be a catchable fatal error instead. This would e.g. make possible to send an e-mail to the developers in case of such an error.

When using object-orientation heavily, a program bug can easily result in an uninitialized or wrongly initialized variable, currently leading to a fatal error. Being able to handle this error case would be a great improvement for quality control.

I hope the implementation of PHP allows such a change.

This request is similar to http://bugs.php.net/bug.php?id=40587 .

In case this request is rejected, please attach a short reason.

Reproduce code:
---------------
set_error_handler( create_function('$code','echo "error handler called ($code)\n";') );
$o = NULL;
$o->method();
echo "end of script\n";

Expected result:
----------------
error handler called (4096)
end of script

Actual result:
--------------
Fatal error: Call to a member function method() on a non-object
