Ticket #105 (closed defect: fixed)
Segfault on getInputLine and getInputChar
|Reported by:||syfran||Owned by:|
Description (last modified by syfran) (diff)
Haskeline gives a seg fault when getInputLine or getInputChar is called.
import System.Console.Haskeline main = runInputT defaultSettings $ getInputLine "$$" >> outputStrLn "Hello World" :: IO ()
This just outputs "Segmentation Fault" when compiled and run (or just quits if run with runghc)
On the other hand,
import System.Console.Haskeline main= runInputT defaultSettings $ outputStrLn "Hello World" :: IO ()
will output "Hello World" as expected.
