Thanks. Hence closing the report.

Debian adds very few changes, and none of them seem likely to be
relevant to this, so I suspect this isn't going to be a productive use
of time.

The Emacs build tree won't react well if you switch in-place between
massively separated git versions. You should do eg a make
maintainer-clean first. Or clone a fresh git directory off the first
one each time.
