Comment (by erikd):

 The error occurs even with `inplace/bin/ghc-stage2 --interactive`.

 Running as `inplace/bin/ghc-stage2 +RTS -Dl -RTS --interactive` it
 finishes off with:

 At first I thought a `start` value of `nil` (as is being passed to
 `addSection` was a problem, but that happens on x86_64 as well, without a
 problem.
