Bug#1059145: libpixman-1-0: arm64 segfault while using proxmox console mode

["Joel May" <debian-bug-report@mail.jmay.xyz>]

I experience this problem too.  In my case, I'm running Debian 12.9 and using virt-manager to view the VNC console of the VM.

I don't know who should own the bug, but I have also filed a bug report on pixman, where I included details of my findings.  It appears to be an out-of-bounds memory access on the source buffer, possibly in function arm_neon_blt.  https://gitlab.freedesktop.org/pixman/pixman/-/issues/119

I was able to work around the problem by removing the Spice display from my VM.  My VM had both Spice and VNC displays.  Even though I was using VNC, the presence of the Spice display seemed to cause the problem.
