Subject: Bug: Can't inherit abstract function

Hi,
the attached script produces:

Fatal error: Can't inherit abstract function Drawable::draw()
(previously declared abstract in Figure) in /usr/home/thekid/r.php on
line 12

which is wrong because I am not inheriting anything but implementing an
interface.

The problem is that both zend_do_inheritance() *and*
zend_do_implement_interface() use (merge_checker_func_t)
do_inherit_method_check.

Want me to open a bug report?
