Starting mclient with any database, and executing:
create table t1 (c1 integer);
insert into t1 values (1);
select sum(c2) from (select count() / (select count() from t1) as c2 from t1) as t;
should yield a single value, of 1. Instead - you get nothing, just a prompt for the next statement. No error message, no result, nothing in merovingian.log .
