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

-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)
-
-Yeah, the page fails uploading the code dump file. Actually it seems to upload the whole file but then it shows a "Timeout error" error. Anyway, let me know if you need that file and if so how can I send it to you.
-
-What's happening here is that the memory range you're asking to dump (physaddrs 0 to 0x3fffffff) includes a lot of devices, including the interrupt controller, which is at 0x1e000000. There's a longstanding bug in the GIC code where it will crash if you try to access its per-CPU register bank from some context that isn't a guest CPU (including the monitor or the QEMU gdb stub), because it doesn't know which CPU's version of the registers you wanted. That's what you've run into here.
-
-However, I suspect you didn't really want to try to take a memory dump of a pile of devices. The RAM in the vexpress-a9 board starts at 0x60000000, so if you wanted the RAM then try
- pmemsave 0x60000000 0x9fffffff memory.dmp
-
-
-LP:1602247 is the bug for the similar issue when using the gdb stub.
-
-
-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.
-
-
-Still valid.
-
-
-
-This is an automated cleanup. This bug report has been moved to QEMU's
-new bug tracker on gitlab.com and thus gets marked as 'expired' now.
-Please continue with the discussion here:
