The original #14120 report was linked to the use of CANNOT_DUMP which is
not used any more, AFAICT, so we haven't really investigated this bug.
Concretely, I don't know how/where this shows up. Do you have some
recipe (and/or backtrace)?

The docstring of `load-history` says that (car load-elt) should never be
anything else than a string or nil. So the right fix is likely
elsewhere.
