#14969: panic on incorrect syntax -------------------------------------+------------------------------------- Reporter: johnleo | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.5 Resolution: fixed | Keywords: TypedHoles Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | ghci/scripts/T14969 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by johnleo): The latest behavior using 8.5.20180413 on my Mac is that if I type `3 _ 4` or `3 _` GHCI now hangs, which I do not consider an improvement over the panic. I have to type `^C` to break. If I type something like `_` or `_ 3` I get a `Found hole` message as expected. Reopening, but if it makes more sense to file a new bug instead I can do that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14969#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
