I can reproduce it with this minimal .emacs:

(global-font-lock-mode t)
(set-face-attribute 'font-lock-doc-face nil :italic t)

Then I load ielm.el, and I do an incremental search of "looking". Doing
several C-s in a row (to move back and forth between the two instances
of `looking-at' on ielm.el), I get a bogus character every time (when
Emacs is displaying the definition of `ielm-return') either on the
line where looking-at appears or the following one.

Changing the second line on my .emacs to set any attribute other than
:italic (even the also-deprecated :bold) seems to not trigger the problem.
