"repeat" sql fails with a column

Dremio 20

create table s3ci.bug."repeattest" as (select 'xyz' as "str" from INFORMATION_SCHEMA.COLUMNS limit 1);

select str from s3ci.bug."repeattest";

-- works
select repeat('abc', 3) from s3ci.bug."repeattest";
select replace(str,str,repeat('abc', 3))  from s3ci.bug."repeattest";

-- does not work, giving a column for arg1 fails with
-- SYSTEM ERROR: ExpressionParsingException: Expression has syntax error! line 1:0:no viable alternative at input 'repeat'
select repeat(str,3) from s3ci.bug."repeattest";

Thanks for the repro steps @benw I have opened an internal ticket
