xfaces.c: error: `ngcs' undeclared

xfaces.c: error: `ngcs' undeclared

[Robert J. Chassell]

Today's GNU Emacs CVS snapshot, Thu, 2005 Feb  3  13:07 UTC
GNU Emacs 21.3.50.45 (i686-pc-linux-gnu, GTK+ Version 2.4.14)

`make bootfast' fails with this error:

    xfaces.c: In function `x_free_gc':
    xfaces.c:741: error: `ngcs' undeclared (first use in this function)

Interestingly, I downloaded an instance of xfaces.c on 2005 Jan 10.
It has compiled OK since, but not this morning.

I then downloaded a new instance.  The new file is identical to the
previous version and generates the same error when I run `make
bootfast' again.

See my message on emacs-pretest-bug.  The problem is clear.  It's just
that Miles Bader and Kim F. Storm seem to disagree on best the
solution.  As a temporary solution, you can revert src/dispextern.h to
the previous version.

Kim Storm just solved the problem.

Thanks!  

Fortunately, a more recent CVS snapshot, Thu, 2005 Feb 3 14:42 UTC
builds without reported error using `make bootfast'.  Kim fixed
xassert.

All looks well.

But be prepared for crashes!!!  Save your work often!

I already had one crash in vertical-motion.

I'm not sure it is valid or bogus assert, but I was not able
to debug it as my gdb session had problems too :-(

Does it disable auto-save mode?  Otherwise, we can depend on Emacs.
Over the past two decades, I have often been auto-saved.

Nah.   Auto-save works fine.  An emacs crash is still annoying, but a
lot less annoying than a crash in most programs .... :-/

I've been running with xassert turned on for a long time, so it's not
too bad -- and it does catch real bugs (several recently, as you can
see on this mailing list).

No.  But still, some work is not always saved (e.g. if you work in a
shell buffer, or while composing a mail message).

Sure.

Mail composition buffers are auto-saved; Gnus also checkpoints its
state whenever you exit a group.  I find the main annoyance is process
state.

One habit I have adopted since using starting to use the development
version of Emacs is creating scratch buffers by doing "C-x C-f
/tmp/foo" rather than just "C-x b foo", which ensures that they're
autosaved too.

Auto-save doesn't guarantee that everything you wrote is saved...
And you process state gets lost.

Also, one thing which has bitten me more than once is while
debugging something with gdb -- if emacs crashes on you,
your gdb session is lost -- any you may have worked for a long
time to get into an interesting state in your program...

Sure, but it gets pretty damn close -- I don't think I've ever lost
more than about half a sentence due to a crash, even if it happens
when I'm actively entering text.

Did you by any chance set `auto-save-interval' to a very small value?

No, it's at the standard setting (300 chars).  You'd think I should
lose an average of 150 characters (about 3 sentences :-), but it never
seems to be that much...
