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)
