  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)
