#4506: program fails with "Segmentation fault/access violation in generated
code"
--------------------------------+-------------------------------------------
Reporter: HolgerReinhardt | Owner:
Type: bug | Status: new
Priority: normal | Component: Runtime System
Version: 7.0.1 | Keywords:
Testcase: | Blockedby:
Os: Windows | Blocking:
Architecture: x86 | Failure: Runtime crash
--------------------------------+-------------------------------------------
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.
