What uses do multi-step dependencies have? As in, I think this goes into the wrong direction, we lived without this since years, so why should this situation be handled at all? It's about cache hash tables, so they shouldn't contain anything that is only pointed to at by entries in those tables. If anything we rather should check, that calling gt_ggc_mx on anything retained in the hash tables doesn't generate newly live objects. Ciao, Michael.
