Hi：
   I find a crash bug, version is  mysql 5.5.8

   Just try:
   use test;

   drop table if exists t1,t2;
   create table t1(a int);
   create table t2(b int);
  PREPAREstmt FROM "select sum(b) from t2 group by b having b in (select b from 
t1)";
   execute stmt;       --  crash
                                                                       zhongtao
