LP:668237 - Assertion `table_ref->has_record' failed in maria-5.3-mwl128 with join_cache_level=4, join_buffer_size=1

Even after the fix for 665057 sql_select.cc:13863: int join_read_key2(THD*, JOIN_TAB*, TABLE*, TABLE_REF*): Assertion `table_ref->has_record' failed in maria-5.3-mwl128, a more complex query:

SELECT t2 .col_int_key
FROM t4
LEFT JOIN t2 JOIN t5 ON t2 .col_varchar_1024_utf8_key = t5 .col_varchar_10_utf8_key ON t4 .col_int_key
LEFT JOIN t3 JOIN t1 ON t3 .col_varchar_10_utf8_key = t1 .col_varchar_1024_latin1 ON t4 .col_int_key = t1.pk
WHERE t2 .pk <> 4 ;

crashes with the same assertion and the following backtrace:
