Ok, rebuilding from scratch doesn't help. The message is almost the
same, though the file may be obscured due to make -j3. With just make
the actual failure is (unsurprisingly) in
dist-stage2/build/BinIface.p_hi.
Apparently there's a do_expr case missing for StgLam in
stgMassageForProfiling, but I could only guess how this could look
like or whether this should perhaps never occur and be converted to a
closure or an StgLet somewhere.

That seems to have fixed one problem, but I now get:

ghc: panic! (the 'impossible' happened)
(GHC version 6.11.20081205 for i386-apple-darwin):
SCCfinal.do_expr
\ [eta_s9gV{v} [lid]] ->
ghc-6.11.20081205:Binary.a74{v r2Y} [gid]
$dBinary37{v r7mT} [gid] bh{v s9fY} [lid] eta_s9gV{v} [lid]
I don't know what caused this, but it appears that SCCfinal has encountered
an StgLam. This isn't supposed to happen, because according to the
comments in StgSyn:
-- StgLam is used *only* during CoreToStg's work. Before CoreToStg has
finished
-- it encodes (\x -> e) as (let f = \x -> e in f)
Cheers,
Simon
