#10602: ghc panic: Template variable unbound in rewrite rule when compiling with -O2 -------------------------------------+------------------------------------- Reporter: pacak | Owner: bgamari Type: bug | Status: infoneeded Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.2-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by thomie): I'm not sure what you're asking. For me, it fails with both `ghc-stage1` and `ghc-stage2` from a devel2 build of HEAD, as well as with `ghc-7.10.1.20150710` from hvr's ppa. If it wasn't clear: you need both `T10602.hs` and `T10602b.hs`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10602#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
