(the 'impossible' happened) -------------------------------------+------------------------------------- Reporter: jachymb | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: duplicate | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by thomie): * status: new => closed * resolution: => duplicate Comment: I'm assuming you are loading this in GHCi. The workaround is to remove the {-# OPTIONS_GHC -O2 #-} from your file. Indeed fixed in 7.10.3. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11157#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
