Just to add to this. I installed Ubuntu 32 bit, and Ubuntu 64 bit (Both
v9.04). Did a Distro install, then did (in each):

apt-get update
apt-get upgrade
apt-get install cvs
apt-get install build-dep gnubg

I pulled out the cvs code from Aug 13th, 2009. Then did

./autogen.sh
./configure --enable-threads

Under 32 Bit Ubuntu everything works. Utilizing 64 bit didn't. I could add
to the database (NO errors adding) but show records would fail with the
attached backtrace.

This doesn't necessarily mean its a 64 bit issue but it suggests that the
problem manifests itself on some distros and not others. It may be some
uninitialized variable issue, some compiler bug, a problem with sqlite3 on
the 64 bit platforms etc. I have never seen a DB issue on any 32 bit builds
(Maybe we've just been lucky in that regard).
