<<loop>> ing program with ghc-7.0.1
I've got a (unfortunately large) program that terminates with <<loop>> if compiled with ghc-7.0.1 but works as expected with ghc-6.12.3 (and ghc-6.10.4).
In order to reproduce this, install the two cabal packages programatica-1.0.0.1 and hana-0.97 (not on hackage)
(I'll try to attach this archives.)
Apply the installed program "hana" to the file "Dummy.hs" inside the hana-0.97 package.
The expected output is:
{-
scope:
-}
module Dummy where
The output produced by hana created by ghc-7.0.1 is
hana: <<loop>>
Some tracing indicated that something goes wrong in the programatica module ScopeModule.
The original problem is reported here: http://trac.informatik.uni-bremen.de:8080/hets/ticket/884
