program fails with "Segmentation fault/access violation in generated code"
I have the following program:
module Main where
import Control.Concurrent.Chan
import Control.Concurrent
import Control.Monad
main = forever $ do
c <- newChan
mapM_ (\ix -> writeChan c "test") [1..500000]
mapM_ (\ix -> writeChan c "test") [1..500000]
c <- newChan
forkIO $ mapM_ (\ix -> writeChan c "test") [1..500000]
mapM_ (\ix -> readChan c) [1..500000]
Compiling and running I get this behaviour:
I:\haskell>ghc -O error.hs
[1 of 1] Compiling Main ( error.hs, error.o )
Linking error.exe ...
I:\haskell>error
Segmentation fault/access violation in generated code
If the program doesn't crash after about 30seconds you may have to cancel and restart it, as it sometimes seems to run forever without crashing.
I have tested the binary on another Windows machine and got the same crash, so a hardware problem seems unlikely.
