On the leaf grid view of a CpGrid with LGRs, there are faces equivalent to the ones from level zero which have not been refined. In particular, when populating face_topoint of coarse faces that happen to touch an LGR on its boundary on (at least) one corner, get the refined corner.
There was a bug assigning -1 in those cases, instead of the actual correct leaf grid view corner index. This PR fixes it.
