Subject: Broken select on regular expression !!!

Hi all,
I think I have found a bug in regexp based selections.
Watch this :
create table regdemo (fld1 varchar(32));
CREATE
insert into regdemo values('410');
INSERT 726409 1
insert into regdemo values('7410');
INSERT 726410 1
insert into regdemo values('source');
INSERT 726411 1
insert into regdemo values('destination');
INSERT 726412 1
select * from regdemo where fld1 ~* '^sou|^des';
fld1
-----------
source
destination
(2 rows)
select * from regdemo where fld1 ~* '41|^des';
fld1
-----------
410
7410
destination
(3 rows)
select * from regdemo where fld1 ~* '^41|^des';
fld1
----
(0 rows)
^^^^^^^^^^^^^^
!?!?!?!
I thought it should return '410' and 'destination' rows. But it returns
nothing!
The first select example with ^ in both variants ( ^sou|^des ) works !!!
The last one ( ^41|^des ) don't !
Am I missing something?
I am getting the same result also on 6.4.2 and 6.5 beta 1 versions!
Best regards,
