While running test/format configurated for backups with develop as of yesterday afternoon, changeset 070b5d8baa it immediately hit this assertion.
__rec_update_save, 35: onpage_upd != NULL || supd_restore
This feels similar to WT-5952, but I opened a new ticket since it is a different path and error message.
Here's the stack:

You can see that both of those were passed in as those values.
