Comment:
Here are some heap profiler reports comparing GHC HEAD with 7.4 when
compiling
Cabal and the single Cabal module Distribution/Simple/Setup.hs.
They are obtained by running:
{{{
ghc -O --make Distribution.Simple +RTS -hc
}}}
and
{{{
ghc -O -fforce-recomp --make Distribution/Simple/Setup.hs +RTS -hc
}}}
respectively, with both compilers built with `-prof -auto` on
`compiler/simplCore/Simplify.lhs`, where the leak seems to be located.
