[Bug 1751674] Re: qemu-system-arm segmentation fault using pmemsave on the interrupt controller registers

[Thomas Huth]

The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting the bug state to "Incomplete" now.

If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".

If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:

1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:

    https://gitlab.com/qemu-project/qemu/-/issues

and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.

2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).

Thank you and sorry for the inconvenience.

Title:
  qemu-system-arm segmentation fault using pmemsave on the interrupt
  controller registers

Status in QEMU:
  Incomplete

Bug description:
  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)
