* src/ftcrfont.c (ftcrfont_open): Initialize the `max_width` field
On a 32bit build, Emacs can otherwise crash with a !FIXNUM_OVERFLOW_P
assertion in `Ffont_info` by simply doing `emacs -Q` and then `C-s`.
* src/font.c: Try and detect uninitialized `max_width` fields.
(font_make_object): Set max_width to a silly value.
(Ffont_info): Check the value is not silly any more.
