#9315: Weird change in allocation numbers of T9203 -------------------------------------+------------------------------------- Reporter: nomeata | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: Component: Runtime | Version: 7.9 System | Keywords: Resolution: | Operating System: Unknown/Multiple Differential Revisions: | Type of failure: None/Unknown Architecture: | Test Case: Unknown/Multiple | Blocking: Difficulty: Unknown | Blocked By: | Related Tickets: | -------------------------------------+------------------------------------- Comment (by simonpj): As well as your last para, you seem to have found that compiling some particular module (is it `Data.Typeable.Internal`?) with -O2 instance of -O1 makes a factor of 2 difference in allocation for at least this test. Is that right? If so, it'd be worth knowing why, and perhaps putting `{-# OPTIONS_GHC -O2 #-}` with a clear comment in that file.
