Continuing (with the help of a condition handler) after a variable initialization has failed crashes the server.
This can happen either with an explicit variable (as in 'p' in the example) or with the implicit variable in the simple CASE statement ('q' in the example).

How to repeat:
delimiter //
create procedure p()
  declare continue handler for sqlexception select 'boo';
    declare v int default x;

    if v then
      select 1;
    end if;
create procedure q()
  declare continue handler for sqlexception select 'boo';

  case x
  when 1 then
    select 1;
  end case;
delimiter ;

call p();
-- restart server
call q();
