Other things as well. The second example came from a completely unrelated app - dnsmasq if I remember correctly. The assertion failures are not deterministic. I do recall the machine was using a fairly substantial amount of swap at the time which might be relevant, as I haven't noted a failure recently since rebooting the laptop. > If this is an application bug, it’s probably due do a buffer overrun > corrupting an adjacent page that contains page run metadata.

I'll keep an eye out for further failures and see if I can figure out a reproduction recipe.
