qemu-system-arm segmentation fault trying to dump VM memory
Status in QEMU:

Bug description:
Qemu segfaults trying to generate a VM memory dump:

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)
