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.
