It works like this: https://qlever.cs.uni-freiburg.de/lindas/5tQs8K |

@ktk Thanks for reporting this! What's even weirder is that with the second query (that works) in the cache, the first query also works. We will investigate! |

There was a bug in the following scenario: a UNION that is lazily computed and at least one of the inputs of the UNION contains a subquery that does not SELECT all possible variables. Then the UNION threw an assertion, because there was some confusion between the number of visible variables in the input (only the ones selected by the subquery) and the actual number of columns in the result (which includes the not-selected variables of the subquery). Fixes #1681
