On an IPv4 system it would be nice if mysqld would start when getting "::" as IP (bind-address) as if it has been started with "0.0.0.0". That would make testing much simpler as mysqld would have been started at all and the IP can be checked in the application (test program). There is unfortunately no variable to check which IP version is active, like e.g. "have_ip_version" delivering 4 or 6.

A patch for this bug has been committed. After review, it may be pushed to the relevant source trees for release in the next version. You can access the patch from: http://lists.mysql.com/commits/92326 2936 Alexander Nozdrin 2009-12-01 A patch for Bug#48915 (After having switched off the ipv6 support in OS, mysqld crashed in network_init()). The problem was that current_thd was not ready at that point in mysqld life, so ER() macro could not be used. The fix is to use ER_DEFAULT() macro, which is intented for such cases.

How to repeat: Switch off the IPv6 support of the Linux ("ping6 localhost" is failing). execute the attached tests with mtr.
