#14496: Invoking GHC 8.2.1 executable anywhere results in access violation on Windows 10 -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Keywords: | Operating System: Windows Architecture: | Type of failure: GHC doesn't work Unknown/Multiple | at all Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- This apparently started to happen somewhat recently, as I've been able to run GHC 8.2.1 on Windows before. (Perhaps it was a recent update that changed things?) In any case, any attempt to run GHC or GHCi 8.2.1 immediately results in an access violation, and always at the same memory location: {{{ $ ghc --version The Glorious Glasgow Haskell Compilation System, version 8.2.1 $ ghc Access violation in generated code when reading 000000001170399e $ ghci WARNING: GHCi invoked via 'ghci.exe' in MinTTY consoles (e.g., Cygwin or MSYS) doesn't handle Ctrl-C well; use the 'ghcii.sh' shell wrapper instead GHCi, version 8.2.1: http://www.haskell.org/ghc/ :? for help Access violation in generated code when reading 000000001170399e }}} Strangely enough, GHC 8.0.2 and older do not suffer from this issue, just 8.2.1. In case it's useful, here's the `strace` output: {{{ $ strace ghc Access violation in generated code when reading 000000001170399e create_child: ghc --- Process 10324 created --- Process 10324 loaded C:\Windows\System32\ntdll.dll at 00007ffa31280000 --- Process 10324 loaded C:\Windows\System32\kernel32.dll at 00007ffa31170000 --- Process 10324 loaded C:\Windows\System32\KernelBase.dll at 00007ffa2dd40000 --- Process 10324 loaded C:\Windows\System32\apphelp.dll at 00007ffa2b500000 --- Process 10324 loaded C:\Windows\System32\AcLayers.dll at 00007ffa03630000 --- Process 10324 loaded C:\Windows\System32\msvcrt.dll at 00007ffa30ab0000 --- Process 10324 loaded C:\Windows\System32\user32.dll at 00007ffa2e850000 --- Process 10324 loaded C:\Windows\System32\win32u.dll at 00007ffa2dba0000 --- Process 10324 loaded C:\Windows\System32\gdi32.dll at 00007ffa2ec30000 --- Process 10324 loaded C:\Windows\System32\gdi32full.dll at 00007ffa2da00000 --- Process 10324 loaded C:\Windows\System32\msvcp_win.dll at 00007ffa2d960000 --- Process 10324 loaded C:\Windows\System32\ucrtbase.dll at 00007ffa2dbc0000 --- Process 10324 loaded C:\Windows\System32\shlwapi.dll at 00007ffa2e7f0000 --- Process 10324 loaded C:\Windows\System32\combase.dll at 00007ffa30e50000 --- Process 10324 loaded C:\Windows\System32\rpcrt4.dll at 00007ffa2e9e0000 --- Process 10324 loaded C:\Windows\System32\bcryptprimitives.dll at 00007ffa2dcc0000 --- Process 10324 loaded C:\Windows\System32\sfc.dll at 0000000180000000 --- Process 10324 loaded C:\Windows\System32\winspool.drv at 00007ffa1db00000 --- Process 10324 loaded C:\Windows\System32\IPHLPAPI.DLL at 00007ffa2cb90000 --- Process 10324 loaded C:\Windows\System32\bcrypt.dll at 00007ffa2d0d0000 --- Process 10324 loaded C:\Windows\System32\sfc_os.dll at 00007ffa1c2e0000 --- Process 10324 loaded C:\Windows\System32\imm32.dll at 00007ffa31220000 --- Process 10324 loaded C:\Windows\System32\shell32.dll at 00007ffa2ef80000 --- Process 10324 loaded C:\Windows\System32\cfgmgr32.dll at 00007ffa2e700000 --- Process 10324 thread 3948 created --- Process 10324 loaded C:\Windows\System32\SHCore.dll at 00007ffa30cf0000 --- Process 10324 loaded C:\Windows\System32\windows.storage.dll at 00007ffa2dfb0000 --- Process 10324 loaded C:\Windows\System32\advapi32.dll at 00007ffa30da0000 --- Process 10324 loaded C:\Windows\System32\sechost.dll at 00007ffa2eb00000 --- Process 10324 thread 4764 created --- Process 10324 loaded C:\Windows\System32\kernel.appcore.dll at 00007ffa2d660000 --- Process 10324 loaded C:\Windows\System32\powrprof.dll at 00007ffa2d5f0000 --- Process 10324 loaded C:\Windows\System32\profapi.dll at 00007ffa2d5d0000 --- Process 10324 thread 3852 created --- Process 10324 loaded C:\Windows\System32\wsock32.dll at 00007ffa1c2b0000 --- Process 10324 loaded C:\Windows\System32\ws2_32.dll at 00007ffa2ef10000 --- Process 10324 loaded C:\Windows\System32\ws2_32.dll at 0000000000150000 --- Process 10324 unloaded DLL at 0000000000150000 --- Process 10324 thread 4872 created --- Process 10324 thread 5780 created --- Process 10324 thread 8360 created --- Process 10324, exception c0000005 at 00007ffa3129c12e --- Process 10324 thread 8360 exited with status 0x1 --- Process 10324 thread 5780 exited with status 0x1 --- Process 10324 thread 4872 exited with status 0x1 --- Process 10324 thread 3852 exited with status 0x1 --- Process 10324 thread 4764 exited with status 0x1 --- Process 10324 thread 3948 exited with status 0x1 --- Process 10324 exited with status 0x1 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14496 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
