#13455: GHCi crash GHC with creation of a "crash dump file" in Windows --------------------------------+---------------------------------- Reporter: vanto | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Keywords: | Operating System: Windows Architecture: x86 | Type of failure: Runtime crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: --------------------------------+---------------------------------- 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 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13455 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
