I am able to narrow down to the minimum configuration you need in your
.emacs file to get this crash (following the steps I had mentioned

I put the following lines in my .emacs, opened xdisp.c file and used
the arrow button to move down the lines. Once the cursor reached the
last visible line, the crash happens (before pulling the new lines
into visible frame).

This crash does not happen with a different font though (like courier)!

(setq inhibit-splash-screen t)
(setq *def-font
  "-*-Lucida Sans Typewriter-normal-*-*-mono-13-*-*-*-c-*-*-*")
(if (boundp '*def-font)
    (add-to-list 'default-frame-alist `(font . ,*def-font)))
