Description of Problem: If LANG is set to en_CA, or when dictonary to use in emacs spell menu was chosen "British" (you need a link for that to provide /usr/lib/aspell/british and I did not try to set LANG to en_GB) then an attempt to run spell check, in emacs - from menu or via 'ispell-buffer' command, on a attached file ends up with: ispell-process-line: Ispell misalignment: word `yer' point 28161; probably incompatible versions and an underlying process is dumped. Try to hit 'a', for "accept", every time when speller has doubts. Depending on other factors some other weird "words" may show up so the trouble may be really not in dictionaries. If "American" dictionary is used or LANG is set to en_US then there are no troubles. As there are less "errors" with "American" then maybe this dictionary kind is really not relevant and there are some overflows in 'aspell'? The attached file is a part of a considerably bigger real paper and it is close to the smallest one which exhibits the problem. That means that splitting this file in pieces and running speller on each piece separately, regardless of which variant of English is used, is not causing any errors. The problem is reported agains current beta but this behaviour is exactly the same at least with emacs and aspell from 7.2 distribution.

Uhh... worked here? Can you reproduce it with a text file?
> Uhh... worked here? Hm, I got the same error across _three_ different machines, two underlying versions of emacs and two distribution variants. Careful! It does work when "American" dictionary is in use, i.e. if 'neighbor' is an acceptable spelling. The current workaround was to set explicitely a dictionary in an emacs startup. > Can you reproduce it with a text file? Sorry, which "text file"? What I attached is a text file but, as I wrote in a report, if you will reduce it further then problem disappears. If you would like the whole original file on which the bug hit for the first time then I have a permission to use it so I may mail it to you. It is somewhere in 100K range. Just ask for it. :-)
With "text file", I was thinking plain text - no LaTeX. I'm able to spellcheck the entire file with limbo (current beta), and was with RHL 7.3 too... (which meant it would try to fix "neighbor" :)
