Reloading edited mutually recursive modules gives error
Given two modules which are mutually recursive, for
instance the following:
<file Boot.hs>
module Boot where
import A
data Data = forall n. Class n => D n
</file>
<file Boot.hs-boot>
module Boot where
data Data
</file>
<file A.hs>
module A where
import {-# source #-} Boot
class Class a where
method :: a -> Data -> a
</file>
Now, if I do 'ghci Boot.hs' this will correctly cause
an error because Boot.hs needs -fglasgow-exts. So I add
{-# OPTIONS -fglasgow-exts #-} in the beginning of
Boot.hs. Finally I do ':r' in ghci. This yields the
following error:
*** Exception: expectJust upsweep_mod:old_linkable
