#15168: GHC HEAD crashes on Windows 64 after the SRT overhaul (May 16, 2018 and newer) -------------------------------------+------------------------------------- Reporter: awson | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.5 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): There's nothing Windows-specific in the GC'ing of CAFs that I'm aware of. There are no Windows-specific conditionals in the SRT code generation, nor in the garbage collector, so I'm mystified about how this is failing. The only wrinkle I know about is the old `COMPILING_WINDOWS_DLL` hacks that we had to support SRT references in another DLL: https://phabricator.haskell.org/diffusion/GHC/browse/master/rts/sm/Scav.c;bf... I removed that code, but it wasn't active in any case because we aren't doing shared libraries on Windows, and as far as I could tell it couldn't have worked anyway because the code generator had no support for generating these references (that part probably got lost earlier). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15168#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
