For the record, this has nothing to do with TTY vs GUI frames.  You
can have the same problem on a GUI frame if you use a bogus symbol for
the fringe bitmap, like 'foobar instead of 'question-mark.


Makes sense.


Evidently, the Founding Fathers never meant for us to use display
properties on after-strings that specify display on the fringe.  Emacs
22 and 23 infloop if you try your recipe on a TTY there.  Emacs 24.1
is the first release that doesn't, and it already has this bug.


The given example uses before-string, but I guess you mean both.
That's odd, though, because when used with overlays, before- and after-strings are the most flexible for this and similar use cases. 


Fixed in 6b765b8 on the emacs-24 branch.


Works fine. Thanks!
