Thanks to Roman's easy repo case I found and fixed this. Please merge:

* FIX #1715: egregious bug in ifaceDeclSubBndrs
ifaceDeclSubBndrs didn't have an IfaceSyn case; but with type
families an IfaceSyn can introduce subordinate binders. Result:
chaos.

I did not add a test case --- too hard!

With package ndp, tickle the bug as follows:
{{{
make build.library.ndp
touch Data/Array/Parallel/Lifted/Closure.hs
make build.library.ndp

Comment (by [EMAIL PROTECTED]):
Meanwhile, I found out that the missing second line isn’t the actual
cause of the bug.
You can do the first build on the original version or on the version with
the second line deleted–compiling of {{{Window.hs}}} will always
succeed. (If you compile with the second line deleted, you will get
errors when compiling {{{OrdinaryWindows.hs}}}, but that’s normal.)
After the first build, you just have to trigger the recompilation of
{{{Window.hs}}} to see the bug in action—you don’t have to change
anything, doing a {{{touch
Haskell/Graphics/UI/Grapefruit/Adapters/Gtk2Hs/Window.hs}}} is enough.

To reproduce this bug, install GHC 6.8.20070916 and Gtk2Hs 0.9.12 as
currently described on http://haskell.org/haskellwiki/Grapefruit#Building.
There is a modified version of the current development version of
Grapefruit attached to this bug report which is needed for bug
reproduction. Sorry, but I wasn’t able to give you a small code example
showing this bug in action since every time I started to reduce the code
significantly, the bug vanished.
Unpack the attached file bug.tar.bz2, enter the directory named {{{bug}}}
and run {{{runghc Setup.lhs configure}}} followed by {{{runghc Setup.lhs
build}}}. Compilation should be successful. Then remove the second line of
the file {{{Haskell/Graphics/UI/Grapefruit/Adapters/Gtk2Hs/Window.hs}}}
and run {{{runghc Setup.lhs build}}} again. Now you should see the
following error messages:
