#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 goldfire): If it's working in HEAD and at the tip of the ghc-7.10 branch, I think it's safe to close the ticket with a regression test. Given the sensitivity of the bug, it might be worth the trouble to make sure that the regression test actually fails on, say, 7.10.2-rc1. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10602#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
