I get a crash at this point using C-x C-e on this line as the first activity in
emacs -Q, after pasting the above into *scratch* and removing the > quotations.

Can you reproduce it by evaluating the following first:

(set-default-coding-systems 'iso-latin-1-dos)

Possibly not, as setting the coding systems to ...-unix does not make the
problem go away for me, and the user who saw the bug on NetBSD/powerpc did not
report doing anything special like this to trigger the bug.
