#8603: GHC crashes on some code using StateT monad transformer ------------------------------------------------+-------------------------- Reporter: person1729 | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler (Type checker) | Version: 7.6.3 Resolution: fixed | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Compile-time crash | (amd64) Test Case: typecheck/should_fail/T8603 | Difficulty: Blocking: | Unknown | Blocked By: | Related Tickets: ------------------------------------------------+-------------------------- Comment (by monoidal): What confuses me is that before the commit 7.7 already did not crash for this program. I checked that a6f6169a9939525c859b274955e8606d6080100f (commit just before yours) and HEAD give the same error message. Was the commit just internal refactoring, or has it visible consequences? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8603#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
