Bug #5691 Segment fault when performing like on mysql.user table

Description:
login to mysql server with mysql client (local socket connection):

mysql>select * from user where host like '%name%';

mysqld_safe segfaults

Note:  REGEXP function also segfaults on this server.
Note:  select * from mytable where name like '%abcd%' does not appear to segfault the server.  REGEXP ALWAYS fails and results in mysqld segfaulting

How to repeat:
just do the select statement

disregard.  Problem goes away with 4.1.5a-gamma
