#12408: "ghc: panic! (the 'impossible' happened)" only when compiled with "-O" -------------------------------------+------------------------------------- Reporter: clinton | Owner: Type: bug | Status: merge Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by simonpj): * status: new => merge Comment: I think this is a dup of #12212. Certianly it works with HEAD; I checked. The fix for #12212 has been merged to the 8.0 branch, I think. I have not checked that it works with the 8.0 branch. I'll set status to 'merge' just to invite someone to test that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12408#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
