See attachment for the result of running `make TEST=conc034 WAY=optasm TEST_HC=ghc-7.10.1.20150715`. It starts with: {{{ *** Core Lint errors : in result of Simplifier *** <no location info>: Warning: In the expression: seq @ e10_a20g @ (# State# RealWorld, () #) e2_a20o (# eta_B1, () #) Kinds don't match in type application: Type variable: b_13 :: * Arg type: (# State# RealWorld, () #) :: # xx # *** Offending Program *** }}} ghc-7.10.1 is fine.
