Re: Emacs crashes, 07nov16

["Robert J. Chassell" <bob@rattlesnake.com>]

Let's try this, using this morning's update of Debian testing and
snapshot of GNU Emacs.  For each backtrace (see below), I evaluated
(x-synchronize t) before visiting the file that would have me print
the Euro sign.

Incidently, when I put 

    (make-char 'latin-iso8859-15 164)

into my *scratch* buffer and evaluated it, the instance continued, as
expected.  When I put `insert' in front of it and evaluated that
expression, the instance also continued, which I did not expect.

When I visited the mail file that contained the expression with the
insert, i.e. ~/foo.mail, the instance crashed, as expected. (As usual,
I produced the backtraces after visiting ~/foo.mail.)
