      Description

      Running test/format with backups, I hit this assertion failure. This is running develop as of right now, changeset 994751e39:

      [1584974735:984619][16062:0x7ff8c67fc700], t, file:wt, WT_CURSOR.insert: __split
      _insert, 1722: unexpected page-delete structure when splitting a page: WT_PANIC:
       WiredTiger library panic
      

      Here's the stack:
