float4/float8 regression failure on Alpha Linux

Hi all,

I am getting a regression failure on float8 (and float4) when running on Debian Sarge on Alpha (gcc 3.3.4). Postgres
is a HEAD checkout from yesterday.

test=# select version();
version
-------------------------------------------------------------------------------------------------------
PostgreSQL 8.0.0beta4 on alpha-unknown-linux-gnu, compiled by GCC gcc (GCC) 3.3.4 (Debian 1:3.3.4-13)
(1 row)

--This test sould give an error
SELECT 'Infinity'::float8 + 100.0;
?column?
----------
0

Is this a problem with my system, Alpha's or postgres.
Thanks
Jim
