Comment (by simonmar):

 Looking at the repro instructions for this bug, it seems the common factor
 is that the bootstrapping compiler is built with no optimisation,
 ''including the libraries''.

 Simon, you could try setting your `build.mk` to "quickest", and add
 `GhcStage3HcOpts = -O2`, then try building a stage 3 compiler, my hunch is
 that this should reproduce it.
