#8848: Warning: Rule too complicated to desugar -------------------------------------+------------------------------------- Reporter: carter | Owner: Type: bug | Status: closed Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 7.8.1-rc2 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | simplCore/should_compile/T8848, | T8848a | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by yongqli): It is possible that {{{ {-# RULE map2 = map2_spec #-} map2_spec :: (a->b->c)-> (Shape Z a )-> Shape Z b -> Shape Z c map2_spec = inline map2 }}} creates an infinite loop, because we end up with {{{ map2_spec = inline map2_spec }}} ? My program seems to hang after trying it, but GHC does not throw <<loop>>. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8848#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
