FWIW, I saw a backend crash in opr_sanity in an otherwise reasonably
successful attempt to build/test Postgres on SPARC/SunOS 4.1.4. This
was with REL6_4 CVS sources around the start of December. I didn't have
time to investigate it closely, but it does seem there's a platform-
dependent problem lurking in there somewhere. (Wonder if it could be
specific to the SPARC hardware?)

Can any of the backend experts make any guesses from Keith's backtrace?
