And that shows that Iʼd forgotten about the tag bits in emacs
integers. 'floor' is trying to convert 1549541220, which is greater
than your most-positive-fixnum.

You can either switch to a 64 bit platform, or try rebuilding emacs
with '--wide-int', which will attempt to use 62 bit integers (or
switch to the unreleased emacs-27, which has essentially unbounded
integers).
