I don’t know if there is an existing object reference crawler, but I ported mine from VW. It finds the shortest paths so it is good for finding the reference that is causing the memory leak.

location: ‘’
user: ”
password: ‘’

Once loaded, you can evaluate something like “ReferenceFinder findPathToInstanceOf: MyClass”. That will return a reference path or nil if no path exists from the Smalltalk global to an instance of MyClass. If you want to find a path to a particular instance, you can use “ReferenceFinder findPathTo: myInst”.
