backtrace and query look similar to the issue we reported leading to the
following commitfest entry:

    https://commitfest.postgresql.org/16/1413/

Our customer hasn't seen any crashes with cube() statements since

    replacement_sort_tuples = 0

I'm afraid this workaround might be needed here as well unless a fix
makes it into 9.6.7.
