GIN bugs in master branch

Suppose, some last changes in GIN are broken, 9.3 works fine.

CREATE OR REPLACE FUNCTION generate_tags()
RETURNS int[]
LANGUAGE SQL VOLATILE AS
$$
SELECT ARRAY(
SELECT
(random()*random()*1000)::int4
FROM
generate_series(1, 1 + (random()*random()*100)::int4)
);
$$;

DROP TABLE IF EXISTS t;

SELECT
i AS id,
generate_tags() AS tags
INTO t
FROM
generate_series(1, 1000000) AS i;

CREATE INDEX tagidx ON t USING gin (tags);

TRAP: FailedAssertion("!(( ( (GinPageOpaque) ( ((void) ((bool) ((!
assert_enabled) || ! (!(((const void*)(page) != ((void *)0)))) ||
(ExceptionalCondition("!(((const void*)(page) != ((void *)0)))",
("FailedAssertion"), "gindatapage.c", 51), 0)))), (char *) ((char *) (page) +
((PageHeader) (page))->pd_special) ) )->flags & (1 << 0) ))", File:
"gindatapage.c", Line: 51)
