[AUCTeX-devel] help please

[Prof. Robert Harper]

i have been happily using auctex with aquamacs on a mac for many years.  
sometime, not long ago, i have the following mysterious problem with the 
compilation mode (double C-c).  here’s a file to demonstrate it:

\documentclass{article}
\begin{document}
foobar
\end{document}

Yes, it is the most trivial file possible!  When I do a C-c C-c and compile 
with LaTeX, I get a successful compile, BUT it reports in the message line

LaTeX: problems after {1} page.

It means that C-c C-C will not cycle through the options to preview, for 
example, because of said problem.

Please advise on what is going wrong!

The log file reveals no particular problems:
