I see, thanks for pointing me in the direction of those commits.
I figured a new version would not have the same issue, so we’ll upgrade.

probably a memory corruption or use-after-free, or
possibly an attempt to use a partially cons

(4.2-3ubuntu6.23~cloud0).
A few of our VMs randomly trigger a segfault in qemu-system-x86_64. This seems
