In other words, I tend to use standard blas or openblas or atlas (but
seemingly less often).  Both are 17.04, but that doesn't matter as they both
have been updated regularly over the years.

You must have gotten out of whack between what compiled R, and what runs it.
Did you by chance compile R 3.4.3 locally?
