I've tested this against both 4.1.9 and current 4.1.11 but could not reproduce the problem

Perhaps it's related to the system collation_* variables below. I can provide a login if that would be useful to you. I've attached our startup script, error log and my.conf. mysql> show variables; ERROR 2006 (HY000): MySQL server has gone away No connection. Trying to reconnect...

When the parameter is converted to utf8 character set, the bug does not manifest, so it's definitely a charset issue: mysql> select concat('!', x) from TEST; +----------------+ | concat('!', x) | +----------------+ | !one | | !onetwo | | !onetwothree | +----------------+ 3 rows in set (0.00 sec) mysql> select concat(_utf8 '!', x) from TEST; +----------------------+ | concat(_utf8 '!', x) | +----------------------+ | !one | | !two | | !three | +----------------------+ 3 rows in set (0.00 sec)

I was unable to repeat the behavior reported with latest BK source server and using your my.cnf file.

Please close the bug then. If anyone experiences the bug they can use the _utf8 fix I wrote about earlier. Thankyou!
