We're scheduling the same SLP node twice from different S= LP instances. We're supposed to merge SLP instances which share nodes though, but we're only doing that for internal defs. We need to either duplicate the constant/external nodes in different subgraphs or merge subgraphs with common constants/externals as well. I'll think about it. This isn't new in GCC 14, it should be a problem since GCC 11.=
