As been discussed on IRC this bug is two different bugs.

First one is server crash with assertion failure

handler/handler0alter.cc:368: virtual enum_alter_inplace_result ha_innobase::check_if_supported_inplace_alter(TABLE*, Alter_inplace_info*): Assertion `key_part->fieldnr < altered_table->s->fields' failed.

to reproduce:

DROP TABLE IF EXISTS t1;
SET SESSION expand_fast_index_creation=ON;
CREATE TEMPORARY TABLE t1 (a INT, b INT, INDEX(a));
ALTER TABLE t1 ADD INDEX (b);

Second one is a warning which was been issued by explain_filename.
