New description:
If use ghci.exe and separating compiling via ghc.exe, memory leak in ghci
occurred. After exhausting available memory Vista has no any respond.
Steps for reproduce:
* Run GHCi: process list has 2 processes: ghci.exe (a), ghc.exe (b),
* Run separated compilation process 20 times:
Command Line:
{{{
for /L %i in (1,1,20) do ghc -fforce-recomp -O --make "problem.hs" -o
"problem.exe"
}}}
Sample Haskell Program listing (problem.hs):
{{{
main :: IO ()
main = do
print $ [x | x <- [1..]]
putStrLn "Hello, world!"
}}}
* In process list (taskmgr.exe) you can see processor activity and
increased value of "Memory (Private Working Set)" for process (b).
* As run result "Memory (Private Working Set)" increased about 100Mb.
