      Description

      When I run test/format with this CONFIG:

      data_source=lsm
      cache=20
      compression=none
      key_max=64
      ops=2000
      rows=100
      insert_pct=45
      leaf_page_max=12
      value_max=64
      

      I see this core dump:

      The problem is that trk->btree->bm is NULL.
