Hi, The behavior of the -N flag (without argument) with the profiling runtime seems inconsistent compared to the behavior without profiling. The following program ``` module Main where import GHC.Conc main :: IO () main = print numCapabilities ``` when compiled with `ghc -threaded -fforce-recomp Prof.hs` and run as `./Prof +RTS -N` prints `2` on my machine. When the same program is compiled with `ghc -threaded -fforce-recomp -prof Prof.hs` and executed as `./Prof +RTS -N` it prints `1`. When an argument is provided to `-N` (e.g. `./Prof +RTS -N2`) the profiling and non-profiling versions behave the same. I tested this with GHC-7.10.1 but I think that I already observed the same behavior with GHC-7.8. Is this inconsistency intended? Lars
