Trying to build from the darcs repository

[Florian Weimer]

How much memory does GHC need to build on amd64 GNU/Linux?  I'm trying
to build from the darcs repository, and this command

"inplace/bin/ghc-stage1" -H32m -O -package-name terminfo-0.3.1.1
  -hide-all-packages -i ilibraries/terminfo/.
  --ilibraries/terminfo/dist-install/build
  -ilibraries/terminfo/dist-install/build/autogen
  -Ilibraries/terminfo/dist-install/build
  -Ilibraries/terminfo/dist-install/build/autogen
  --Ilibraries/terminfo/.  optP-include
  -optPlibraries/terminfo/dist-install/build/autogen/cabal_macros.h
  -package base-4.2.0.0 -package extensible-exceptions-0.1.1.1
  -split-objs -Wall -XForeignFunctionInterface -XDeriveDataTypeable
  -XEmptyDataDecls -XScopedTypeVariables -XFlexibleInstances -O2
  -XGenerics -fno-warn-deprecated-flags -odir
  -libraries/terminfo/dist-install/build -hidir
  -libraries/terminfo/dist-install/build -stubdir
  -libraries/terminfo/dist-install/build -hisuf hi -osuf o -hcsuf hc
  --c libraries/terminfo/./System/Console/Terminfo/Effects.hs -o
  -libraries/terminfo/dist-install/build/System/Console/Terminfo/Effects.o

needs more than 3.5 GB of RAM.  Or is this some sort of miscompilation
problem?  (I'm trying to bootstrap with GHC 6.12.1, but saw this with
GHC 6.8 as well.)

The start of the context is this:
