Re: BUG #1015: Got a signal 11 while trying to create a temp table

How do I get a "debugger backtrace" ?

Selecting all data from the tables involved, does that also include a 'coun=
t(*)', if so, they work:

stats=3D# select count(*) from blocks;
  count
---------
 3194409
(1 row)

stats=3D# select count(*) from hosts;
 count
-------
   205
(1 row)

stats=3D#

Yours,

Aarjan
