Compiling some source files with ghc -fglasgow-exts -O2
and some with GHCi results in GHCi panic. No FFI used
in source.

See attached tarball for source files and walkthrough.

ghc-6.2.1: panic! (the `impossible' happened, GHC
version 6.2.1):
        Bytecode generator can't handle unboxed tuples.
 Possibly due
        to foreign import/export decls in source. 
        compile this module to a .o file, then restart

Please report it as a compiler bug to,
