Hi folks,
I've got stacked now because of a time leak problem with integral.
The following program leaks CPU-time gradually:
> import FRP.Reactive
> import FRP.Reactive.LegacyAdapters
> import Control.Applicative
> type Velocity = Double
> type Position = Double
> data Car = Car { vel :: Velocity, pos :: Position } deriving Show
> velocity :: Behavior Velocity
> velocity = 1
> position :: Behavior Position
> position = integral (atTimes [0, 0.5 ..]) velocity
> car :: Behavior Car
> car = Car <$> velocity <*> position
> main :: IO ()
> main = adaptE $ print <$> car `snapshot_` atTimes [0, 0.5..]
1) why is the leak happen?
2) how can I fix this problem?
Some more detailed informations:
* reactive 0.11.4
* GHC 6.12.1
* Gentoo Linux (2.6.32-tuxonice, x86_64)
* compiled with or without -O2 flag
Thanks,
