PostgreSQL version: 9.0.1
Operating system: windows 7
Description: Server crash with function out params returned as record
Details:

create or replace function test(out integer, out numeric)
as $$
select (1, 2.1)
$$
language sql;

test=# select * from test();
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.

LOG: server process (PID 3336) was terminated by exception 0xC0000005
HINT: See C include file "ntstatus.h" for a description of the hexadecimal
value.
LOG: terminating any other active server processes

When I chanage the function body to:
select 1, 2.1
it works as expected.

test=# select version();
