Seeing the same thing on Darwin 5.5/OSX 10.1.5 with the latest CVS code
(well, latest as of this morning, 8/7/2002). trying to run the code
from the README file in /ext/overload with the php CLI executable, i
get a bus error. this is what i see in gdb, after running configure
with --enable-debug added:
Starting program: /usr/local/book/php/bin/php mydb.php

The overload extension is enabled by default on PHP-4.3.0-Dev with
Zend2 alpha 1 AND 2 on windows, but the overload() function does not
work. At times it crashes Apache, other times it gives a message like
'too many nested levels'.
class test {}
overload('test'); // <== Crashes PHP
I guess it happens because of the new way PHP handles objects - we no
longer need to call $this->function(), so how would the overloaded
class decide wich function or property to work with?
Also, when overloading methods only the first function call is
overloaded. When an overloaded function is called from within another
one, it is not found. I think this behavior is fine for properties, but
it limits the use of the extension when using overloaded methods.
(should this be in another bug report or feature wish list?)
