I can confirm this, too.
I had a CVS update and a 'make bootstrap' today.
To reproduce the problem just try to load a file.
It crashes every time.
I also have a Windows client. Does this happen on other platform(s) ?

Bela

On GNU/Linux, tab-width is 8 by default.

You mean `M-x load-library RET edebug RET' in `emacs -q' produces a crash?
Does not happen for me on GNU/Linux.
So, at first view, it looks like an MS Windows specific problem.
Sincerely,
Luc.

It seems that
FRAME_SPACE_WIDTH (it->f)
is zero (i.e. it->f->space_width is zero)
While debugging and changing this to anything but zero
the crash goes away.
This space_width - according to the Changelog - is a
relatively new code (added by Kenichi Handa on 2004-12-30)
Could it be the problem that it is not initialized ?

So, I think you are using Emacs on Mac or Windows. And, as
I found these changelogs in today's emacs:
2005-01-03 Jason Rumney <jasonr@gnu.org>
* w32bdf.c (w32_load_bdf_font): Set fontp->average_width and
fontp->space_width to FONT_WIDTH so they are valid.
* w32fns.c (w32_load_system_font): Set FONT_WIDTH to maximum, not
average width. Set fontp->average_width and fontp->space_width to
their appropriate values.
* w32term.c (x_new_font): Set FRAME_COLUMN_WIDTH to
fontp->average_width, not FONT_WIDTH. Set FRAME_SPACE_WIDTH to
fontp->space_width.
2005-01-03 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
* macterm.c (x_new_font): Set FRAME_SPACE_WIDTH.
(x_font_min_bounds, XLoadQueryFont): Use the correct font width
metrics for max and min bounds.
(x_load_font): Correctly calculate average font width metrics.
perhaps the problem is already fixed.

That's true. However I updated my files on 2005-01-03. Probably
the fix got into CVS later that day.

This is also correct. With these changes the crash didn't appear again.
So problem solved. Thanks.
