Execute SQL:
create table runcat (id int not null, dp double not null);
SELECT r.* FROM runcat r GROUP BY;

mserver5 output:

could not find r.dp
mserver5: rel_bin.c:2234: rel2bin_project: Assertion `0' failed.

r.* is now handled as *, ie lookup the columns (in the group by intermediate). In this case that is only the id column
