Well, after I poked some more at this bug, it seems that it's not
actually fixed after all. After consultation with Yosi, it seems the
code that checks for these cases happens during output (serialization)
rather than during parsing. Therefore, log:sematicsOrError will be
connected to invalid semantics, whereas we really want it to be
connected to an error statement.
I've checked in a test set in test/syntax/bad-preds*.n3 that should
probably be the benchmark for this bug. I've also added a (commented
out) test definition in regression.n3.
