osprey dumped core on 8.2

Osprey is a NetBSD running on m68k

http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=osprey&dt=2007-02-22%2023:00:18

It dumped core running VACUUM:

--- 1,5 ---- VACUUM;
! server closed the connection unexpectedly
!     This probably means the server terminated abnormally
!     before or while processing the request.
! connection to server was lost


The stack trace report looks incomplete:

================== stack trace: pgsql.27009/src/test/regress/tmp_check/data/postgres.core ==================
Core was generated by `postgres'.
Program terminated with signal 11, Segmentation fault.

546            if (set->blocks != NULL)

It's missing the "bt" part.


I don't understand how can this happen, given that "set" cannot be NULL
at this point.
