--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed, mine.  We're scheduling the same SLP node twice from different SLP
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.
