#13381: "opt_univ fell into a hole" panic from rewrite rule -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.1 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 goldfire): To be clear, the `opt_univ fell into a hole` bit is a red herring here. The real problem is that the type-checker doesn't reject the program. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13381#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
