Before we close this, I suggest that you try reproducing again, after
removing the *.eln files from your eln-cache.  Basically, as more and
more *.eln files are produced and deposited there, the lower the
probability of seeing any problems with native compilation, since
Emacs stops compiling stuff because it already has what it needs.

(But if you already tried that and still failed, then OK, let's close
this issue.)

Thanks.
