#9031: ghc panic: RegAlloc.Liveness.computeLivenss ---------------------------------------+----------------------------------- Reporter: jwlato | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time crash | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ---------------------------------------+----------------------------------- Comment (by jwlato): Paul, thanks very much. I've created a self-contained test case based on your code (I believe it's the same issue I'm having). When I try to compile the attached files with {{{ ghc -O2 Top.hs }}} I get the same error. One interesting thing is that this error seems to require that `pawnAdvanceSquares` is called in multiple locations, even though in the generated core it only appears once. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9031#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
