It's when you have two objects A and B, each referring to the other and no other object in memory pointing to one of them. Old GCs had problem with that because they used reference counters. In this case, the counters equals to one in both objects whereas the GC collects only objects with a zero-count. -- Damien Cassou Peter von der AhÃ©: Â«I'm beginning to see why Gilad wished us good luckÂ».

Hi Laurent, I loaded your XML-parser and ContIntegration in a fresh Pharo image. None of the test contained in CITestReporterTest pass. Am I doing something wrong?

Making it run for pharo-dev one it works for pharo should be trivial. I guess that Damien will be interested in that.

We had the occasional problems that we just couldn't find were an object is hold on to. Suspect were terminated processes and theirs stack, blocks or similar, but as I said, we couldn't figure it out occasionally. It's been a long standing problem with Smalltalk though, I remember having that problem way back with ObjectWorks. Michael

This is exactly what I thought at first, but I still see some instances lying in my image, I am indeed using dependents but I take care of releasing it. Hilaire

You normally don't need to nil out the variables unless you want to make sure that an object is easily recognized as invalid (e.g. you check for nil values elsewhere). When objects don't get garbage collected they often are registered somewhere as dependents, in caches or similar places. Michael

What is cycle of unused objects? Circular references of unused objects? What I did, for the Drgeo canvas, when the user ask to dismiss it, I am releasing and forcing to nil the instance variables. But it brings other problems. I ma curious to know how developers handle this problem. Sorry I am a bit off-topic.
