Hello,
I'm running emacs-24 branch as of Fabrice Niessen's commit :
Author: Fabrice Niessen <fniessen@pirilampo.org>
Date: Mon Sep 29 16:30:16 2014 +0400
Check in accumulated leuven-theme updates before it's too late
* themes/leuven-theme.el: Updates.
Here's a recipe for getting to an eassert violation in pop_it (xdisp.c):
run: emacs -Q ~/tmp/bug2.org -f visual-line-mode -f org-indent-mode -f end-of-buffer -f org-content
where bug2.org is the attached file (I gzipped it)
[-- Attachment #2: bug2.gz --]

[-- Attachment #3: Type: text/plain, Size: 1561 bytes --]
then place mouse cursor in the blank area after the last line (let's say
right under "(xxx)") and scroll down with the mouse (i.e. turn the wheel
up). I usually get the crash immediately, or sometime after scroll-up
then down again.
Here's the gdb session :
(gdb) r -Q ~/tmp/bug2.org -f visual-line-mode -f org-indent-mode -f end-of-buffer -f org-content
Starting program: /home/youngfrog/sources/running-emacs/src/emacs -Q ~/tmp/bug2.org -f visual-line-mode -f org-indent-mode -f end-of-buffer -f org-content --eval '(sit-for 3)' -f scroll-down

Do you need "set solib-search-path" or "set sysroot"?

FWIW the bug is still present on the pretest, and was not present in

Sorry, I somehow completely missed your original report. (And thanks
for an easy-to-follow recipe.)
This is now fixed on the emacs-24 branch (r117536).
