We have some code in the Clash compiler to do with dynamic linking, which I expect is TH-related: https://github.com/clash-lang/clash- compiler/blame/d7dfef9d89b30d096370887899be24b9027914ac/clash-ghc/src- ghc/Clash/GHC/LoadModules.hs#L174-L179
{{{ let ghcDynamic = case lookup "GHC Dynamic" (DynFlags.compilerInfo dflags) of Just "YES" -> True _ -> False let dflags3 = if ghcDynamic then DynFlags.gopt_set dflags2 DynFlags.Opt_BuildDynamicToo else dflags2 _ <- GHC.setSessionDynFlags dflags3 }}}
I don't have access to an OS X machine, so could you check if setting
#15105: `typecheckModule` from GHC API crashes on MacOS for files with TH ----------------------------------+---------------------------------------- Reporter: harpocrates | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: GHC API | Version: 8.4.2 Resolution: | Keywords: Operating System: MacOS X | Architecture: Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ----------------------------------+---------------------------------------- Comment (by harpocrates): Replying to [comment:2 darchon]: the {{{Opt_BuildDynamicToo}}} flag fixes the TH issue? I just tried this on OS X and it unfortunately makes no difference: in either case, `lookup "GHC Dynamic" (DynFlags.compilerInfo dynflags')` produced `Just "NO"` (and then manually enabling `DynFlags.Opt_BuildDynamicToo` also didn't change anything). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15105#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
