Since cmd/vet uses go/types, this may be the same corruption observed in #37602.

These are all the possible failures I see in the build logs.

I couldn't find any recent occurrences of this, so closing the issue as obsolete. The most similar one I saw was this one, where it seems to be running out of memory:
