#10574: «the 'impossible' happened» when compiling singletons -------------------------------------+------------------------------------- Reporter: zardoz | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: duplicate | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by goldfire): * status: new => closed * resolution: => duplicate Comment: This is likely a duplicate of #10251, fixed for GHC 7.10.2. In the meantime, if you say `--ghc-options=-O1` when installing via `cabal`, you should be able to get past this error. I am closing this ticket as a duplicate. If you think this is in error, please reopen. Thanks for reporting! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10574#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
