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))
