#12491: ghc-iserv pattern match failure -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- While trying to debug the issue in https://ghc.haskell.org/trac/ghc/ticket/11981#comment:10 I found that that `ghc-iserv` executable run without any arguments fails with a pattern match failure: {{{ $ inplace/lib/bin/ghc-iserv ghc-iserv: user error (Pattern match failure in do expression at iserv/src/Main.hs:28:3-18) }}} Would be far nicer if it printed out an error message saying what arguments it expected, or how to run it to avoid this pattern match failure. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/12491> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
