    It's a use after free bug in the ddx, presumably. I haven't worked out how
    yet since all active buffers should be appropriately marked. So either
    there is a race in marking the buffer, or we failed to handle an error
    appropriately or there is a real use-after-free. The kernel is being
    gracious enough to warn you why userspace just crashed.
