Unable to find table executing CTE

[Trying-1831]

Details

I have a SELECT statement that executes without error. When I embed the statement in a CTE, I get the message:
[13:12:37] Error while executing SQL query on database 'VX': no such table: MX.Chimp

Steps to reproduce

SQL:
select cID, VUID, mcKey,email, phone, cell
from MX.Chimp
where addr1 is not null

CTE:
with tmp(cID, VUID, mcKey, email, phone, cell) as (
select cID, VUID, mcKey,email, phone, cell
from MX.Chimp
where addr1 is not null
)
select * from tmp

An additional test - I am executing in the active database with:
select a.abc from dbn.table - this works, but
with h as (select a.abc from dbn.table) select * from h; -- fails

with h as (select a.abc from table) select * from h; -- works

It looks as though there is a problem using fully qualified table names in a CTE.
