I have upgraded to Cabal 1.2 while still using GHC-6.4.1. In the Haskore project there is the module NewResolutions.lhs which let GHC run into extensive swapping (certainly due to excessive memory consumption) on compilation when compiled with optimization. One can say, it cannot be compiled this way. This is clearly a compiler bug, but upgrading the compiler is not an option here. Thus I used unoptimized compilation so far. Now, Cabal 1.2 seems to have optimization set by default. While it was easy to add optimization by using 'GHC-Options' field it is not obvious how to override Cabal defaults.
How about an OPTIONS -Onot pragma in the affected source file?
I like to do it this way, but that pragma seems not to override the global Cabal setting. I added
{-# OPTIONS_GHC -Onot #-}
to the top of the module and I also added an invalid option, which let the compiler fail, so this pragma is indeed processed.
(Putting optimization options in GHC-Options is now discouraged.)
Hackage upload told me about.
