#13750: GHC produces incorrect coercions in hairy code -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: #13429 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by kosmikus): I can confirm that `-fno-specialise` also works in the full example as a workaround (but it seems it has to be applied at each use site of one of the critical functions, so it's not an extremely viable workaround for a library). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13750#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
