irreproducible python31x failures on NetBSD/i386

[Thomas Klausner <wiz%NetBSD.org@localhost>]

I was asked to look at the python312 and python313 failures in this bulk build.

I installed (both from scratch) first NetBSD 9.4/i386, then 9.0/i386
inside qemu and built both python* packages from the pkgsrc-stable
branch. It worked fine for me.

qemu command lines:

9.0:
qemu-system-i386 \
        -accel nvmm \
        -m 4G \
        -name "NetBSD 9" \
        -object rng-random,filename=/dev/urandom,id=viornd0 \
        -device virtio-rng-pci,rng=viornd0 \
        -device virtio-net,netdev=n0 \
        -netdev tap,fd=3,id=n0 \
        -drive file=NetBSD-9.0.qcow2,if=none,id=hd0 \
        -device virtio-blk-pci,drive=hd0 \
        -display curses \
        3<>/dev/tap0

9.4:
qemu-system-i386 \
        -accel nvmm \
        -m 4G \
        -name "NetBSD 9" \
        -object rng-random,filename=/dev/urandom,id=viornd0 \
        -device virtio-rng-pci,rng=viornd0 \
        -device virtio-net,netdev=n0 \
        -netdev tap,fd=3,id=n0 \
        -drive file=NetBSD-9.qcow2,if=none,id=hd0 \
        -device virtio-blk-pci,drive=hd0 \
        -display curses \
        3<>/dev/tap0

Dependencies were installed from ftp.netbsd.org with pkgin (with the
defaults provided by sysinst).

Inside the 9.0 image:

python313:
$NetBSD: Makefile,v 1.7.2.1 2025/01/02 12:41:05 bsiegert Exp $
$NetBSD: distinfo,v 1.3.2.1 2025/01/02 12:41:05 bsiegert Exp $

python312:
$NetBSD: Makefile,v 1.23.2.1 2025/01/02 12:41:10 bsiegert Exp $
$NetBSD: distinfo,v 1.11.2.1 2025/01/02 12:41:10 bsiegert Exp $

-rw-r--r--  1 root  125  44918518 Jan  6 13:36 /usr/pkgsrc/packages/All/python313-3.13.1nb2.tgz

qemu is 9.1.1nb2 and runs on NetBSD 10.99.12/amd64, but that shouldn't
really matter.

Does anyone have an idea what could be the problem here?
