Hi,

Currently the way I have to reproduce it is:

- install the regression database
- drop all tables but: 
    hash_i4_heap, hash_name_heap, hash_txt_heap,
      quad_poly_tbl, road
- run 10 sqlsmith processes... normally in an hour or less the problem
  appears

I have the logs from the last time it happened so maybe I can trace the
exact pattern to reproducite at will... at least to keep a test
somewhere.

BTW, so far so good with your last fix (about 12 hours now)...
