I even installed 4GB of RAM to my development machine last year to be able to reproduce this, but I can't, even when the memory allocator is under heavy load. The only people who see this effect are Pedro Ribeiro and William Light (both in Cc:), and both have been very helpful in trying patches and reporting back in detail. Which instructions could we probably give to these people to finally hunt this issue down?
