I only noticed the object when the error appeared, so I'm not sure about the actual sequence. It's not easy to get a legitimate Insufficient Memory error by accident. I tried provoking one on my Mac by starting with a short list containing just a few reals and then doing ENTER EXTEND over and over. I pushed to the point where the app was using 40 GB of memory and it still kept going, just becoming ridiculously slow because of paging and because of having to allocate hundreds of millions of objects each time through the loop. The Windows version is a 32-bit app so it runs out of memory earlier, being limited to 2 GB regardless of how much virtual memory the OS can make available, but even there, it's not something that seems likely to happen unless you're deliberately trying to make it happen. |
