#9416: newArray# incorrectly inlines big arrays (overflow1.hs SIGSEGVS on ./validate --slow) -------------------------------------+------------------------------------- Reporter: slyfox | Owner: tibbe Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Easy (less than 1 Type of failure: | hour) None/Unknown | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by tibbe): If we disable `shouldInlinePrimOp` altogether we get this Cmm: {{{ R1 = (-40); Sp = Sp - 8; call stg_newByteArray#(R1) returns to c3Nu, args: 8, res: 8, upd: 8; }}} Presumably `stg_newByteArrayzh` interprets its argument as an unsigned quantity and thus the test passes without `shouldInlinePrimOp`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9416#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
