I have noticed that objects will sometimes spontaneously change their
print names in MCL 2.0p2 on a MacIIx.
For example, I have a class of objects called answer-node. I have not
defined a print-object method for answer-node. While my program is
running, it prints out statements such as:
Moving node #<ANSWER-NODE #x4E21A1>
However, when I use the inspector later to look at the same object, it
is has a different name: #<ANSWER-NODE #x4DF259>.
I am not able to reproduce this behaviour with any consistency, but I
am convinced after several episodes and much debugging that this is
My question is: is this a known behaviour? If not, is someone
prepared to assert that something else is going on such that the
object whose name is printed is not eq to the object I later inspect,
and that I should just look harder for it?
