#14777: panic when using a function defined in terms of `error` -------------------------------------+------------------------------------- Reporter: zilinc | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Linux | 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 monoidal): I have simplified a bit further, to 2 files; can be reproduced with {{{ ghc-8.2.1 --make Cogent/Desugar -fforce-recomp -O2 }}} This doesn't appear on ghc 8.4 - likely this was fixed. However, the panic depends on many conditions, even small changes to code can make it disappear, so it might be worth further investigation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14777#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
