#16063: ghc-8.6.3 + Mac OSX + FFI dependency causes 'impossible happened' compiler failure -------------------------------------+------------------------------------- Reporter: benselfridge | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by harpocrates): * cc: harpocrates (added) Comment: I can replicate and have a story for what is going wrong here, which involves 3d17f1f10fc00540ac052f2fd03182906aa47e35. I'll prepare a patch shortly, but testing it might be a bit frustrating (I doubt `grift`'s dependencies all easily build on HEAD). I'll try to put together a more minimal test case too. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16063#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
