#16406: Array code works with GHC 8.4.4, hangs with GHC 8.6.4 -------------------------------------+------------------------------------- Reporter: arybczak | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: libraries | Version: 8.6.4 (other) | Resolution: | Keywords: array Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): That's bad. We should not be changing Haskell's semantics, unless the library was somehow exploiting an undocumented (or perhaps even wrong) corner of the semantics. Worth investigating! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16406#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
