strangely enough, now that I've recompiled the program cabal does pass the correct flag and everything works as expected.

Yes, that is in ghc-options and therefore only does something when you compile; it's not consulted at runtime (indeed, running a program doesn't even look at the cabal file).

Not really. -with-rtsopts is a linking-time flag that sets the default RTS options. See http://www.haskell.org/ghc/docs/7.6.3/html/users_guide/runtime-control.html#...

Oh, I think I misunderstood what you're saying. You were pointing out that Alfredo didn't recompile his program. I thought you're saying that this isn't supposed to work at all. Sorry for the noise. Roman
