Then my assumption was wrong.
Here is the entire function and it fails with the names
c2,c2div,c3,c3div, but if names are changed, it works!
(by works I mean I get the "hello" lines printed) There is nothing
wrong with the select statement either, that works fine if I run it
stand-alone, or with the names of c2,c2div,c3,c3div changed.

CREATE OR REPLACE FUNCTION foo(pid_ INTEGER) RETURNS void AS $$
DECLARE
    c2 REAL;
    c2div REAL;
    c3 REAL;
    c3div REAL;
    weights RECORD;
    tmp RECORD;
    retval RECORD;
    t RECORD;
BEGIN
RAISE NOTICE 'starting...';
    FOR tmp IN SELECT id,c2,c3 FROM Master  WHERE pid=pid_  AND c3 !=0 LOOP
        RAISE NOTICE 'hello %',tmp.id;
    END LOOP;
    RETURN;
END; $$  LANGUAGE plpgsql;
