So I tried to approach it from the other side: Building postgresql
with CFLAGS=-O0 -g or -O1 -g works correctly, but with -O2 -g I
get above bug.
Just FAOD, building with gcc 4.1 and -O2 works fine. I guess this
sufficiently proves that this is a gcc 4.2

All the other diffs that Martin showed are divide-by-zero failures,
and I do not see any of them on Gentoo's machine. I think that this
must be a compiler bug. The first example in his diffs is just
select 1/0, which executes this code:

I don't have access to a machine on which the failure occurs, but
perhaps Martin can try it. I'd think it'd be pretty easy, say

Heya,
I know I'm quite late with my answer, sorry.

Hi Tom,

Bottom line is that I see nothing here that the Postgres project can
fix --- these are library and compiler bugs.
Thank you for your detailled analysis! I'll file bugs to the
appropriate places then.
Thanks,
Martin

It looks to me like Debian's compiler must be allowing the division

Can you create a stand-alone testcase for this?
