#13210: Can't run terminfo code in GHCi on Windows -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Runtime System | Version: 8.0.2 (Linker) | Resolution: | Keywords: Operating System: Windows | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3154 Wiki Page: | Phab:D3155 -------------------------------------+------------------------------------- Changes (by RyanGlScott): * owner: Phyx- => (none) * status: closed => new * resolution: fixed => Comment: Alas, it seems like this code is once again broken. On GHC 8.2.1 and 8.2.2-rc3, running: {{{ $ runghc -lncursesw Terminfo.hs }}} In MSYS2 simply exits early with exit code 127, and in PowerShell, it crashes with the following pop-up window: {{{ [Window Title] ghc.exe [Main Instruction] ghc.exe has stopped working [Content] A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. [Close program] }}} Using Phyx-'s modified GHC 8.3 build, running that same command produces a stack trace: {{{ $ ..\..\..\Software\ghc-8.3.20171021\bin\runghc -lncursesw .\Terminfo.hs Access violation in generated code when reading 0xffffffffffffffff Attempting to reconstruct a stack trace...
