#1647: Using -fdicts-strict flag causes Core Lint error
-------------------------------------------+--------------------------------
Reporter: [EMAIL PROTECTED] | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler | Version: 6.7
Severity: minor | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: | Architecture: Unknown
-------------------------------------------+--------------------------------
It appears that passing in the {{{-fdicts-strict}}} flag results in a Core
Lint error for any program:
{{{$ ghc -fdicts-strict -dcore-lint hello.hs }}}
{{{*** Core Lint Errors: in result of Desugar ***
{-# LINE 3 "hello.hs #-}:
[RHS of $dMonad_a6a :: GHC.Base.Monad GHC.IOBase.IO]
Recursive or top-level binder has strict demand info: $dMonad_a6a
Binder's demand info: T}}}
The flag is documented only minimally, so I'm not sure whether it's
something that still gets used a lot. Thus I'm not sure whether it would
be worth it to fix it or just remove the flag. This is only in HEAD.
