server crash: displaying sqlerrm in exception block

PostgreSQL version: 8.2.1
Operating system: Fedora 3
Description: server crash
Details:

I have compiled postgres 8.2.1 with gcc 4.1. and when executed this function
it crashes the server.

i also fetched the code from postgres repository (8.3devel) and tested this
code but it still crashing server.

Steps to produce
----------------------

CREATE OR REPLACE FUNCTION func2() RETURNS int as $$
BEGIN
RAISE EXCEPTION 'ex -----';
EXCEPTION
WHEN OTHERS THEN
RAISE INFO 'sql error msg %',sqlerrm;
DECLARE
v_msg VARCHAR(200) := sqlerrm;
BEGIN
RAISE INFO 'sql error msg %',sqlerrm;
ENd;
RETURN 0;
END;
$$ LANGUAGE plpgsql;

select func2();

Output
---------
INFO: sql error msg ex -----
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
