#13215: Panic: push_bang_into_newtype_arg -------------------------------------+------------------------------------- Reporter: nad | Owner: mpickering Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): What is the fix? Generally we are transforming {{{ f !(F n) = ... }}} into {{{ f (F !n) = ... }}} What if it's this? {{{ f !(F {}) = ... }}} We do still need to be strict. So perhaps we transform to {{{ f (F !_) = ... }}} Looks ok to me (with a Note). Could you execute on that? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13215#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
