More infinite simplifier bugs?

So a while back Simon added a tick counter to the simplifier:
Are there any known bugs that can cause the simplifier to run out of
memory /without/ hitting the tick counter limit?
I have code that /used/ to run (at least after hacking around the
previous simplifier bug):
With GHC 7.4., it exhausts all the RAM on my machine (4GB).
Compiling with -O0 fixes the problem. I can start bisecting my code
to find the problem if nothing comes to mind.
(who seems to be good at killing the simplifier)
