#7057: Simplifier infinite loop regression --------------------------------+------------------------------------------- Reporter: ronwalf | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.4.2 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: Compile-time crash | Testcase: Blockedby: | Blocking: Related: | --------------------------------+------------------------------------------- GHC gets stuck in the simplifier when compiling the attached file, eventually exhausting all ram. Compiling gives: {{{ $ ghc -v3 -O --make ghcloop.hs Glasgow Haskell Compiler, Version 7.4.2, stage 2 booted by GHC version 7.0.3 ... *** Simplifier: ^C*** Deleting temp files: ... }}}
Running with with all the dump flags suggests the fault is pddlDocExpr's. I'm finding it hard to create a smaller example, as even silly things like removing the container (or not using Data.Generics) restore termination. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7057> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
