What is the meaning of the console message: "snarfed from ivar layout ..."?

Question

I have a console message that seems to be triggered by explicitly related events.

The message says:

snarfed from ivar layout: [propertyName] = [constantString]

Where [propertyName]is the name of the property to which I set the value of the string constant [constantString].

What causes this message and what does it mean?
