View with inet6 fields

I have two views with inet6 fields and one view depends on the other. Creating a mariadb-dump and then importing the dump i got the error:

ERROR 4078 (HY000) at line 81: Illegal parameter data types int and inet6 for operation 'coalesce'

How to reproduce the error:

MariaDB [(none)]> create database ipv6;
Query OK, 1 row affected (0,003 sec)

MariaDB [(none)]> create database ipv7;
Query OK, 1 row affected (0,001 sec)

MariaDB [(none)]> use ipv6;
Database changed
MariaDB [ipv6]> create table ips ( ID int unsigned not null default 0, ip inet6 default NULL, primary key(ID));
Query OK, 0 rows affected (0,054 sec)

MariaDB [ipv6]> create view v2 as select ID, min(ip) as ip from ips group by ID;
Query OK, 0 rows affected (0,029 sec)

MariaDB [ipv6]> create view v1 as select coalesce(v2.ip, ips.ip) as ip from ips left join v2 using(ID);
Query OK, 0 rows affected (0,026 sec)

MariaDB [ipv6]> exit
Bye

> mariadb-dump -u root -p ipv6 >dump.sql

> mariadb -u root -p ipv7 <dump.sql
