Ahem. Yes, that's a bug all right. How embarassing.
I've fixed it, but won't be able to commit the fix till I get
back at the end of this week. Meanwhile, use 'data' instead of
'newtype' as a workaround.
Thanks for reporting this, and for boiling it down to something small.

Just a small note: Changing PP from a datatype renaming (newtype)
to an algebraic datatype (data) or inlining ppThen helps...
Cheers,
S.

The GHC from HEAD (Feb 28) crashes, too, even without -O. :-(
No idea why, but -v tells me that it is the first simplifier pas
