New description:

 I have the same program using both ghci and ghc.  ghci gives:

 {{{

 ghc-6.4.2: out of memory (requested 1048576 bytes)
 }}}
 and ghc gives:
 {{{
 ghc -ignore-package Cabal --make -Wall -fno-warn-unused-matches -cpp -i.
 -odir dist/tmp -hidir dist/tmp Setup.lhs -o setup
 ghc-6.4.2: out of memory (requested 1048576 bytes)
 }}}
 I have 2 gigs of ram, and 3 of swap.  When I run ghci, my free memory
 quickly drops from ~1.9 Gb to less than 10 Mb, at which point, I get the
 out of memory error.
 I'm running gentoo on my laptop, with gcc 4.1.1 and kernel 2.6.17-rc1-mm2
