Обсуждение: Yet another regression issue with Fedora-10 + PG 8.4 beta1

Hi,

I built PG 8.4 beta1 on 2 different Fedora-10 boxes. One of them was a
local box, which runs under QEMU. The other one is Fedora's build
servers. (I did a scratch build on Fedora build server)

On the first machine, I got a regression failure:

http://www.gunduz.org/temp/regression.out
http://www.gunduz.org/temp/regression.diffs

I could not repeat this with 2nd one (Fedora build servers)

Any ideas what might have caused it?

Regards,

QEMU screwing up the handling of floating-point traps, perhaps?

Probably. Let me dig it.

Thanks.
