10.1 also fails, but differently, see MDEV-9129 (10.1 fails both on debug and release builds, while 10.0 only fails on release).

To reproduce, download and unpack ftp://ftp.askmonty.org/public/MDEV-9129_data.gz

create table t1 (groups varchar(255) DEFAULT NULL) ENGINE=InnoDB;
 
load data local infile 't1.data' into table t1;
 
ALTER TABLE t1 ADD FULLTEXT ft_qu_la_contacts_groups (groups);

Default server settings are enough.

MDEV-9148: Assertion `thd->stmt_arena != thd->progress.arena' failed in thd_progress_init

Called thd_progress_init() from several threads used for FT-index
creation. For FT-indexes, need better way to report progress,
remove current one for them.
