GC leaks memory under -threaded
The following program leaks 2Mb/s under Windows:
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.10.4
$ cat Test.hs
import System.Mem
import Control.Monad
main = forever performGC
$ ghc --make Test.hs -threaded
$ Test.exe
This leak does not occur if you remove the -threaded
, or if you run the same test on Linux. I am using forever
to leak memory more quickly, but I believe the same issues will arise if performGC
is called in the normal course of a program.
I consider this leak to be critical, so have marked severity appropriately.
