#15570: Core transformations generate bad indexCharOffAddr# call -------------------------------------+------------------------------------- Reporter: alpmestan | Owner: alpmestan Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by alpmestan): * owner: (none) => alpmestan * milestone: => 8.6.1 Comment: I'm going to try and characterise where both builds differ, using `-dverbose-core2core`. The best theory at this point is that libraries are built with different enough options that this affects the optimisation pipeline on this example. This won't be the end of the story though, as we simply ''never'' want to end up with the Core for `f` mentionned above. But at that point we will also have a lot more information about how the Core evolves. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15570#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
