Is the segfault in the
          for (;;)
            {
              if ((*mem_chain)->elt == v)
                {
                  unchain_one_elt_list (mem_chain);
                  break;
                }

              mem_chain = &(*mem_chain)->next;
            }
loop (or, does the #c5 patch from that PR fix it)?
