#12522: GHC 8.0.1 hangs, looping forever in type-checker -------------------------------------+------------------------------------- Reporter: clinton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jstolarek): Surprising. I was expecting that GHC will hang on a black-hole but this indeed looks like an infinite loop in the type checker. I'm afraid Simon or Richard will have to take a look at this. Oh, and `f` need not be a part of a type class. It can be a standalone function with undefined definition. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12522#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
