#7729: GHC panics. Invalid core -----------------------------------------------------+---------------------- Reporter: Khudyakov | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.6.3 Component: Compiler | Version: 7.6.2 Resolution: | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Difficulty: Unknown Testcase: indexed_types/should_fail/T7729,T7729a | Blockedby: Blocking: | Related: -----------------------------------------------------+---------------------- Comment(by monoidal): For the record, I confirm that ekmett's program and the original ticket concerns exactly the same bug, fixed in HEAD. Both programs can be reduced to http://hpaste.org/88612, which crashes 7.6 and gives occurs check in 7.7. I don't think this bug is worth hunting and releasing another 7.6.x - I would close it. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7729#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
