#7850: Strangely high memory usage on optimized Ackermann function ---------------------------------+------------------------------------------ Reporter: dolio | Owner: Type: bug | Status: patch Priority: normal | Milestone: 7.6.3 Component: Compiler | Version: 7.6.2 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: Runtime performance bug Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Changes (by simonmar): * status: new => patch * milestone: => 7.6.3 Comment: As noted earlier, it's already fixed in master. I don't remember when I noticed the bug and fixed it, the fix seems to have come in with the giant patch to rewrite the RTS Cmm files in the new syntax. Anyway, attached is a patch for the 7.6 branch that fixes it. I'll let the release engineer decide what to do with it :-) -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7850#comment:29 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
