Hmm, alright, well, this is at least not the fault of the patch of mine
which was included in Debian's 8.1.2-2 Postgres release. :) You might
try compiling some debs with debugging enabled. This is (reasonably)
straight-forward:

(as root:)
aptitude install build-essential debhelper cdbs bison perl libperl-dev \
tk8.4-dev flex libreadline5-dev libssl-dev zlib1g-dev \
libpam0g-dev libxml2-dev libkrb5-dev libxslt1-dev python-dev \
gettext bzip2 fakeroot
(as user:)
apt-get source postgresql-8.1
cd postgresql-8.1-8.1.0
export DEB_BUILD_OPTIONS="nostrip"
dpkg-buildpackage -uc -us -rfakeroot

Should produce .debs in the parent directory which have debugging
information. Another useful build option is "noopt", ie:
export DEB_BUILD_OPTIONS="nostrip noopt", though that could make the
error go disappear. It'd be terribly nice if you could do this and
provide a gdb backtrace with debugging... :)

Thanks,
