#12775: T3424 hangs with -fregs-graph -------------------------------------+------------------------------------- Reporter: tjakway | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: T3424 | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The -fregs-graph option causes rts/T3424 to hang. I waited 15+ minutes when compiling with inplace/ghc-stage2 before killing it; when run with the test suite after a similarly long time I get a compile failed (exit code 99) message. It passes when run in ghci or when using the default register allocator. To reproduce: make TEST=T3424 EXTRA_HC_OPTIONS=-fregs-graph -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12775 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
