userstat ON prevent using mysql_install_db

[Olivier Doucet]

I have userstat = 1 in my.cnf
Using Percona-Server-5.5.24-rel26.0, launching mysql_install_db leads to error (segfault).

GDB gives me the following :

(gdb) run --defaults-file=/etc/my.cnf --bootstrap --basedir=/usr --datadir=/srv/mysql --log-warnings=1 --loose-skip-innodb --user=mysql --max_allowed_packet=8M --default-storage-engine=myisam --net_buffer_length=16K

Disabling userstat when doing mysql_install_db worked.
