Yeah, ugh. What's irritating is that this is not incorrect - invoking
warn_alloc() in such a way that it does literally nothing is not right, so
that fix was required, but it simply exposed another issue.
But completely agree this is technically a regression, and yes Andrew it'd
be great if we could move this to hotfixes and append the stable cc if
possible thanks!
(We definitely need to refactor a lot of this code!)
