This check is always false because of the undefined behaviour rule that says a NULL pointer must never be dereferenced: we already dereference name when checking the cache slot, before the NULL check. So the NULL may be optimised away by the compiler. It looks like the code isn't even supposed to work with name being NULL, so just remove the check.

There was a problem hiding this comment.
Might make sense to add a ZEND_ASSERT(name); at the top of the function.

Two minor cleanups, descriptions:
This check is always false because of the undefined behaviour rule that
says a NULL pointer must never be dereferenced: we already dereference name
when checking the cache slot, before the NULL check. So the NULL may be
optimised away by the compiler. It looks like the code isn't even

Remove always-true check in zend_fetch_static_property_address_ex()
Simplify always-true conditions.
