Right, that's the problem -- apparently it isn't unchanged in this case
as the diff of the executables' objdump shows.

My hypothesis is that x-win.eln changes between builds (print-circle
etc.) => make-fingerprint computes a different ingerprint and so on.

But that's a hypothesis, I can't check that on my system.
