[php-src] Issue #8041: php 8.2.0-dev crashes with assertion for cloning/get_object_vars on non-empty SplFixedArray (8.1 unaffected)

Issue: https://github.com/php/php-src/issues/8041 Comment Author: dstogov The real problem is SplFixedArray that reuses properties for something else. I'll try to take a deeper look before "fixing" the engine for one weird class. In any case, for `zend_objects_clone_members()` I would prefer to split the loops for MAP and unexpected PACKED arrays. Your second example actually asserts not in `get_object_vars() but in spl_fixedarray_object_get_properties()`. I prefer not to touch other places before we confirmed failures.
