--- Comment #4 from janus at gcc dot gnu.org --- (In reply to Dominique d'Humieres from comment #3) > Revision r241395+patch (2016-10-21) is OK, r241433+patch (2016-10-21) gives > the ICE. AFAICT the only possible revision is the range is r241403. However > in the patches of r241433 I have the patch for r241450 (pr69834), but it > looks also unrelated. I actually think that r241450 might be more relevant here than r241403 (in particular since it messes with gfc_find_derived_vtab).
