qemu-system-arm segmentation fault using pmemsave on the interrupt controller registers
Qemu segfaults trying to generate a VM memory dump:
$ QEMU_AUDIO_DRV=none qemu-git-src/arm-softmmu/qemu-system-arm -M vexpress-a9 -smp 4 -m 1024 -machine secure=off,dump-guest-core=on -kernel linux-4.9.75/arch/arm/boot/zImage -append "root=/dev/mmcblk0 rw rootfstype=ext4 mem=1024M net.ifnames=0 console=ttyAMA0" -dtb vexpress-v2p-ca9.dtb -sd armv7-hd.qcow2 -netdev tap,ifname=tap_armv7,script=no,downscript=no,id=net0 -device virtio-net-device,mac=00:DE:AD:BE:FF:02,netdev=net0 -monitor stdio -serial vc -loadvm SS0

It's the second time I try to submit this bug, I think last time it failed because the attached core dump size (400M compressed). Have a look if you can get that file, otherwise I will try to update this ticket once it's created:
