After playing a bit with that, it seems that it is not
moose specific. I
have maybe an idea about the origin of the Problem:
I have a package, Merlin, which is usually saved in is own repository,
www.squeaksource.com/Merlin.
I had to make some changes on Merlin, and during all this time, I saved all
the 'dummy versions' of Merlin in another repository:
www.squeaksource.com/DelaunayTmpStuffs.
Now, if I compare the latest version from those two repositories:
in www.squeaksource.com/Merlin, BEFORE CHANGES , the offset of the
instance variable causing the problem is 10.
in www.squeaksource.com/DelaunayTmpStuffs, AT THE END OF CHANGES , the
offset of the instance variable causing the problem is 15.
The problem will only happen when merging those two versions. If you load
the version directly from DelaunayTmpStuffs, all will be ok.
If you load the version directly from DelaunayTmpStuffs *in a clean pharo
image*, all will be ok.
Then, I don't know how the information about the
instance variable offsets
is propagated along the different versions of a package. But it seems that
when merging, the information (telling that the offset of the variable has
changed) has been lost in all the version of DelaunayTmpStuffs

We should check the Moose overrides?
is there somewhere a method adding behavior to
behavior and friends?
I did not get the time to have a look.

when evaluating the accessor, it return nil.
