Hah, so that maybe explains why thorntail has only shown this in
the v12 branch. Should we consider back-patching that?
The more general issue of how to detect, or else make safe,
pallocs in critical error reports remains. But I bet any answer
we think of for that will not be back-patchable. So back-patching
a localized fix for the specific bug we know of might be worth doing.
