Public bug reported:
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

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:
(Error ID: OOPS-65553b72bc14be693eb1e37814ff9267)
