Crasher in CVS code on Win2k

Crasher in CVS code on Win2k

[Andrew Hyatt]

I'm using Win2k (service-pack 2).  Occasionally (once every few days)
emacs crashes on me.  I'm not using the absolute latest CVS sources,
but I already updated and rebuilt once to see if this problem goes
away and it hasn't yet.  

Luckily, I have VC++ installed, so here is some info on why it
crashes.

It crashes in w32bdf.c, in get_cached_font_char
The fontp->chtbl is invalid (an obviously bad pointer value of 17),
which is what is causing the crash.  
The stack is:
get_cached_font_char
get_bitmap_with_cache
w32_BDF_TextOut
w32_text_out (here I see that the bad fontp is coming from a variable
which is s->gc->font->bdf, where s and s's gc, look ok, but the gc's
font looks corrupted (for example the font_type is 789185035, and both
the font's bdf and the per_char seem invalid))
x_draw_glyph_string_foreground
x_draw_glyph_string
x_draw_glyphs
x_draw_phy_cursor_glyph
x_display_and_set_cursor
x_update_window_end
update_window
update_window_tree
update_window_tree
update_frame

Our main current Emacs-on-Windows person is currently off the net, and
no one can debug this unless it fails for him.  You may have to debug
this yourself.

    I'm using Win2k (service-pack 2).

In hacker terminology, calling something a "win" is a form of praise.
If you wish to praise Microsoft Windows, you're free to do so; but if you
don't, then you might want to think twice about using the term "win2k".

FWIW, I'm using the CVS HEAD on the same set up (W2K) and I haven't had
a crash in months.
