#13429: Optimizer produces Core with an infinite <<loop>> -------------------------------------+------------------------------------- Reporter: lehins | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 7.10.4 Component: Compiler | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: #13750 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Further to comment:17 I have made no further progress, and now I'm away for a week. Hmm. I think that disabling specialisation (by `specImports`) for imported dictinoary functions would probably cure it, at some modest cost in optimisation. Might be worth a try as a temporary expedient. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13429#comment:22 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
