Dear Bug Team!
Summary: reloading a changed file that includes eval statements
causes the font-lock to fail.
How to recreate:
* cat > test.tex <<EOF
\documentclass[twoside,12pt]{article}
\usepackage{amssymb}

\begin{document}

\pagebreak
This is a test document

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% eval: (reftex-set-cite-format 'natbib)
%%% End:
EOF
* Open test.tex in xemacs
* run 'touch test.tex'
* C-x C-f test.tex
* You will be asked "File test.tex changed on disk. Reread from disk?
(yes or no)"
* Say yes
* You will be asked "Process `eval' or hook local variables in file
test.tex? (y or n)"
* Say y
* At this point, one of two things will happen;
* This warning will be reported: (warning/warning) Error caught in
`font-lock-pre-idle-hook': (wrong-type-argument markerp nil)
* The "Fontifying test.tex" progress bar will appear and stop moving
* In either case, the font coloring does not work in the buffer until
you kill the buffer and reload.
Other relevant information
* I realize I am using an old version of xemacs, but I have recreated
the same bug in the same way with the latest xemacs available on
Debian Unstable (21.4.17-1)
* I am using auctex
Please let me know if I can provide additional information.
