---------------------------------------------------------------
This is not TDB related. See attached files D.ttl and Q.rq
he issue seems to be that the DISTINCT variables and the ORDER BY do not align
so the "reduced" assumption is invalid. Maybe it just needs to test that the
ORDER BY covers the DISTINCT projection.
Running from the command line:
{noformat}
sparql --data D.ttl --file Q.rq
{noformat}
{noformat}
sparql --set arq:optDistinctToReduced=false --data D.ttl --file Q.rq
{noformat}
gives different answers (the second is right, the first has duplicates).
