Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. emacs -q  ispell-bug.tex &

where ispell-bug.tex contains the following:

======8<==========8<============8<=====================
\documentclass{report}
\begin{document}
grux
an orange \ref{one-dictionary}
\end{document}
======8<==========8<============8<=====================

2. M-x ispell-buffer RET
3. SPC (to leave "grux" unchanged)
Message: Spell-checking done
4. M-x ispell-buffer RET
5. SPC (to again leave "grux" unchanged)

This yields an error:

ispell-process-line: Ispell misalignment: word `sgml' point 86; probably 
incompatible versions

$ /usr/bin/ispell --version
Ispell compatibility script for Aspell.
Usage: /usr/bin/ispell [options] -a|-l|-v[v]|<file>

This is from aspell-0.33.7.1-9 on Red Hat.  If I add

1.5 M-: (setq ispell-program-name "aspell") RET

I still get the same error.

$ aspell --version
@(#) International Ispell Version 3.1.20 (but really Aspell .33.7.1 alpha)

(I haven't tried with a real ispell.)  I expected it to just work
without any errors, at least when I told it to use aspell.
