[AUCTeX] strange "LaTeX: problems after {1} page"

[jfbu]

Hi,

I have a (very) strange problem with a (minimal) test file for xelatex

Loading /Users/xxx/yyy/auto/testxetex.el (source)...done
Loading /Users/xxx/.emacs.d/elpa/auctex-11.90.0/style/article.elc...done

LaTeX: problems after {1} page

This is with TeXLive 2017 (in pretest). The log contains no
indication of any error.

The exact same file with TeXLive 2016 gives:

LaTeX: successfully formatted {1} page

and the log appears to be the same as with 2017 apart from the
date changes.

There isn't in the 2017 version an error which is not in the 2016
version. (I diffed)

As my test file uses \XeTeXtracingfonts=1, I wondered if exit
status of XeTeX has changed which would explain new behaviour of
auctex. But it seems not (here with TL2017)

$ xelatex testxetex.tex ; echo $?
...
Transcript written on testxetex.log.
0

so it seems not to be that.

For what it is worth I am attaching the logs (and test). But as you will
see the logs seem to have only innocuous differences.

Here is the test file

\documentclass{article}
\XeTeXtracingfonts1

\usepackage{fontspec}

\setmainfont{TeX Gyre Termes}

\setsansfont{DejaVu Sans}

\setmonofont{FreeMono}

\begin{document}

\rmfamily Hello

\sffamily Hello

\ttfamily Hello

\thispagestyle{empty}

\end{document}

% Local Variables:
% TeX-engine: xetex
% End:

But to reproduce my exact same set-up you need a Mac OS and you need
to have put into ~/Library/Fonts two symlinks

  TeXOpenType -> /Library/TeX/Root/texmf-dist/fonts/opentype
  TeXTrueType -> /Library/TeX/Root/texmf-dist/fonts/truetype

(for FreeMono, you need to "deactivate in FontBook the ttf and
activate the otf", but well...)

I am currently with 11.90.0.

Best

Jean-François
