#11742: 'Strict' extension is incompatible with 'deriving' mechanism -------------------------------------+------------------------------------- Reporter: awson | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by awson): I tried it on quite recent ghc-8.1.20160317. Another thing I've forgotten to mention is that the bug needs `-O` to manifest itself. With no optimizations it doesn't happen. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11742#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
