> Yes, I understand. What kind of code are you looking for then? You have already answered, in a way. You need complex code that runs for a lot of time, while keeping the total amount of memory used constant. You also surely need some synthetic tests, to spot eventual bugs better. I don't know if I have code for you, probably not. Indeed the Olden benchmarks stress the GC, but only its performance, not its precision...
