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/2737

Fixed in 5.1.7, existing in 5.1.6 . Crashes only in debug builds when the separator between DO and the body is not a space :
CREATE EVENT some ON SCHEDULE AT NOW() DO   <--here we have a new line
begin select 1; end|

Noted in 5.1.7 changelog.

          Creating an event and using a whitespace character other than
          space following the <literal>DO</literal> keyword caused a
          server crash. (Bug #17453)
