Reproduce how?  What is the recipe for reproducing this?

*** Open Emacs in an NT cmd shell prompt. In Emacs, open up a cmd shell prompt. 
Start something that will cause a huge amount of text and scrolling. I run a 
build in the command prompt and then just wait for it to crash.

> #0  0x01259f9f in append_glyph (it=0x82ad3c) at term.c:1491

In this frame #0 of thread 1, what do the following commands produce?

  (gdb) print glyph
  (gdb) print i
  (gdb) print it->area
  (gdb) print it->glyph_row->used[it->area]

(gdb) f 0
#0  0x01259f9f in append_glyph (it=0x82acec) at term.c:1491
1491    in term.c
(gdb) print glyph
$1 = (struct glyph *) 0x0
(gdb) print i
$2 = 0
(gdb) print it->area
(gdb) print it->glyph_row->used[it->area]
$4 = 0

Not only, that, but also the -nw session doesn't even access the clipboard.

Where does this message come from?  Do you perhaps have some clipboard-related 
utility installed that is not part of the default Windows configuration?

*** That is the UI based alert that pops up on a crash when the debugger is not 
attached. I have EmacsW32 installed here for Emacs23 but I am not suing that 
and I have no global path pointing to that installation. There is nothing in my 
service list that shows as Emacs either except the application itself.
