GHCi crash GHC with creation of a "crash dump file" in Windows

Hi,\\ I repeated this several times in order and GHC crash after typing the command :r several times in GHCi\\ If the two files are taken separately there is no crash\\

file test1.hs

main :: IO ()
main = do {
             putStr "hello";
             x <- getChar;
             putStr "x = ";
             print x;
           }

file test2.hs

putStr :: String -> IO ()
putStr [] = return ()
putStr (x:xs) = do putChar x
                   putChar '\n'

putStrLn :: String -> IO ()
putStrLn xs = do putStr xs
                 putChar '\n'

1- open GHCi\\ 2- :load test1.hs\\ 3- run main\\ 4- :load test2.hs\\ 5- an error message comes then type :r\\ 6- keep trying :r until the crash of GHC. usually at the end of the third time.\\ 7- see the Windows message to the screen.\\

a "crash dump file" is created. It say:\\ exception code 0xC0000096\\ process name: ghc.exe: C:\ghc-8.0.2\bin\ghc.exe\\ information: the thread tried to execute a statement that the operation is not allowed in the current mode of the computer\\ modules name:\\ ghc.exe, ntdll.dll, kernel32.dll, gdi32.dll, user32.dll, advapi32.dll, rpcrt4.dll, msvcrt.dll, shell32.dll, shlwapi.dll, wsock32.dll, ws2_32.dll, nsi.dll, imm32.dll, msctf.dll, lpk.dll, usp10.dll, comctl32.dll, ole32.dll, userenv.dll, secur32.dll, apphelp.dll\\ a particularly pointed to by Windows file is msvcrt.dll\\

Hope this help
