start to investigate?

Hi,

This is with the most recent multi-tty emacs, so forgive me if this bug
is cause by errors in that branch but I guess it happens in normal emacs
just the same.

It is repeatable: I have a 2.5Mb TeX file which I frequently commit to
cvs. After a commit cvs changes the tag and you have to reload the file
from disk. Emacs notices the change on disk and suggest to reload it
automatically and after confirming with y I get the crash.
