File testdata/workloads/functional-query/queries/QueryTest/nested-types-runtime.test:

Line 427: select count(a.pos) from complextypestbl t1
straight_join?

Also, I'm not sure this is going to be enough rows to reliably reproduce the problem: the
issue occurred when there were multiple build rows per probe row and the same probe row was
returned in multiple batches. I think if the build side is > batch_size it will be a more
reliable repro.
