#10247: 5x increase in total memory allocation for `prof-doc-fib` test since 2011 -------------------------------------+------------------------------------- Reporter: thomie | Owner: Type: task | Status: new Priority: high | Milestone: Component: Profiling | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): I tried running the tests with 7.8.4 since I don't have HEAD built with profiling libraries at the moment. I see almost exactly 2x factors on T680, prof-doc-last, and scc003. I also notice that these prof files are all from Oct 25-27 2011. Probably they were just generated on a 32-bit processor? For prof-doc-fib I notice that the profiling output changed in a recent (not in 7.8.4) commit daed18c35cda114d8a5303bcb645195e1fd397e3, and the old file agrees with the above. That is, it showed almost exactly half the total allocation that I see, and it is from the same date range. So there seems to be no alarm through 7.8.4. I'll try HEAD to see if there is any change. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10247#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
