Fixed! Test is spec003
It was a bug in the specialiser.

* Fix Trac #1402: typo in specialiser
This patch fixes a plain bug in the specialiser (rhs_bndrs instead
of rhs_ids) which made GHC crash in obscure cases.
It exposed a case in which we might not do all possible specialisation;
see Note [Specialisation shape]. It's not an important case, but I've
added a warning in DEBUG mode.
