#7788: Recursive type family causes <<loop>> -------------------------------------+------------------------------------- Reporter: shachaf | Owner: simonpj Type: bug | Status: new Priority: high | Milestone: 7.10.1 Component: Compiler | Version: 7.6.2 (Type checker) | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: Incorrect | Related Tickets: result at runtime | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by thomie): * priority: normal => high Comment: The program from the description compiles fine with 7.8.3. GHC HEAD (ghc-7.9.20141121) however uses a huge amount of memory very quickly until I have to kill the process. It seems to never get past the `Renamer/typechecker` phase. This looks like a regression, setting priority to high. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7788#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
