Context:
It looks like the latex-mode flymake diagnostic function, tex-chktex,
widens before sending the buffer contents to the external linter
process. So the line numbers of errors are reported relative to the
widened buffer, not the narrowed buffer. A number of different checkers
in Emacs seem to do the same thing.
The bug is that these checkers call flymake-diag-region to translate the
line numbers into buffer positions. But flymake-diag-region does not
widen the buffer when doing this translation, so it fails.
I expect you have some flymake logs of the form "Invalid region line=%s
col=%s". when triggering this bug.
Probably the right fix in flymake is to make flymake-diag-region widen,
as in the patch I posted, but that's a bit of a behavior change... will
think about it, but it's probably fine.
