Verified.
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.

Sorry for this, but I am not used to this bugtrucker yet, anywho proper script
should look like that:
$fileIterator = new FilesystemIterator(__DIR__,
FilesystemIterator::KEY_AS_FILENAME);
$regexpIterator = new RegexIterator($fileIterator,
'#.*#',
\RegexIterator::MATCH,
\RegexIterator::USE_KEY
);
foreach ($fileIterator as $key => $file)
{
}
No idea why this `doubled`.
