Please review patch for bug#43488

[Lars-Erik Bjørk]

Ladies and Gentlemen,

Would two of you please take the time to review my patch for bug#43488  
( http://bugs.mysql.com/bug.php?id=43488 ) available at
http://lists.mysql.com/commits/68732 
. Especially, I would like to get confirmation that I release records  
in the catch clause in IndexWalker::getValidatedRecord correctly (or  
incorrectly :) ).

Best,
Lars-Erik
