Comment 3 for bug 452116

Right. The problem is that mysql_install_db never gets around to creating the initial root user; the server segfaults when it processes mysql_system_tables_data.sql.

mysql> CREATE TEMPORARY TABLE tmp_user LIKE user;
Query OK, 0 rows affected (0.00 sec)

mysql> set @current_hostname= @@hostname;
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE TEMPORARY TABLE tmp_db LIKE db;
Query OK, 0 rows affected (0.00 sec)

mysql> INSERT INTO db SELECT * FROM tmp_db WHERE @had_db_table=0;
ERROR 2013 (HY000): Lost connection to MySQL server during query

I'm building a newer package at the moment from lp:~maria-captains/maria/maria-5.1-merge revno 2788. We'll see if the problem persists.
