SIGSEGV in sebselect.

Hi All,

I'm getting a SIGSEGV with the following subselect:-

select * from disks where diskid in
 ( select distinct diskid from tracks where artist = 'Led Zeppelin');

The source tree is a cvsup from 22nd Feb (AM GMT)
Platform is Linux/SPARC

I'm afraid my debugging skills are limited to generating a backtrace
so here goes....

Keith.
