Cannot read beyond the end of buffer on Opteron (and yes, pa


#1

Hi guys.

I’m trying to get Ruby working properly on a Opteron (Ubuntu LTS server)
system. It’s actually a Rails project, but I believe my problem to be
specifically related to Ruby and not necessarily Rails.

When I run “rake migrate”, I get the following:

rake aborted!
Buffer::EOF: cannot read beyond the end of buffer: SELECT
a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = ‘departments’::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum

I did some research and found that this has been a known issue on 64bit
systems, and found the patch here (
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/180119). I
then
downloaded Ruby 1.8.5, verified that pack.c was already patched, and
compiled. It compiled and installed just fine, but I still get the same
error.

Can someone please tell me what I might be doing wrong?

Thanks!
Jake

Responding to myself here…it was actually a problem with left over
files
from the 1.8.2 deb packages I had installed previously. Once i blew
those
completely away with dpkg --purge, I was good to go. Strange but true.

Thanks,
