| Is there any chance there is a bug in recent GHCs (or perhaps Linux?) | affecting this? I'm fairly sure I've lately seen Haskell programs | consuming significantly larger amounts of memory than they should be | allowed to, and I can try to isolate a test case if it is of | interest. New bugs are always possible! And in the last few months, Simon has been doing fairly major surgery on parts of the runtime system, as part of getting multiprocessor-GHC to play nicely. So if you can find a test case where GHC is generating code that uses a lot more memory than it used it, it would be very valuable to us. Thanks! Simon
