ifup -a on aarch64 fails with segmentation fault in v3.0 (buildroot 2018.08, busybox, glibc)

I'm guessing this is caused by the recent switch to glibc from uclibc.

Cannot reproduce on pure upstream buildroot master 9152387703707bd1c8c49e7978ef47aec3f8baeb (post 2019.02) on Ubuntu 18.10 host:

make qemu_aarch64_virt_defconfig
make menuconfig
make BR2_JLEVEL="$(nproc)"
qemu-system-aarch64 \
    -M virt \
    -append "root=/dev/vda console=ttyAMA0" \
    -cpu cortex-a57 \
    -device virtio-blk-device,drive=hd0 \
    -device virtio-net-device,netdev=eth0 \
    -drive file=output/images/rootfs.ext4,if=none,format=raw,id=hd0 \
    -kernel output/images/Image \
    -netdev user,id=eth0 \
    -nographic \
    -smp 1

Edit: reproduce problem on tag: 2018.08 I can't find with git log --grep the commit that fixed it easily however, so I'll just update buildroot when new tag comes out.

Fixed by upgrade to 2019.11 for unknown reasons: ae17a79
