Comment(by MikolajKonarski):
JaffaCake: to avoid messing up the terminal when the crash happens, change
the line
display area = D.display area . fst
to
display area _ a1 a2 a3 = D.startup (\ vty -> D.display area vty a1 a2 a3
>> D.shutdown vty)
in src/Display.hs in the Allure source code. Then press the dot key
repeatedly, as before. Works for me, though it can crash your whole
terminal emulator under right conditions, I'm sure.
