The zend_object_iterator_funcs.dtor function (implementation: spl_filesystem_tree_it_dtor) seems faulty. In the reproduce script here, the zend_object_iterator is requested twice: first by the RegexIterator constructor, and then by foreach. The zend_object_iterator returned is the same in both cases -- that owned by the FilesystemIterator and its destructor gets called twice. But obviously the destructor is not prepared to be called twice as it unconditionally calls zval_ptr_dtor (for some reason, twice) and zeroes the reference to the owning object. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
