Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-4271 .
The bug was introduced in pre-1.8.9 under ZBX-4158, so this is a blocker for 1.8.9rc1, which was planned to be released tomorrow (http://twitter.com/#!/zabbix/status/124100757766160384). Thanks, Alexey!

Alexey, the patch does not affect MySQL connectivity in any way. If you still have those errors with the latest trunk (the memory leak fix has already been merged), please provide a longer excerpt from the log file.
Sorry, Aleksandrs, my mistake... I found bug in MySQL config file:) Patch working excellent
