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.
So it looks like methods which are not changed by a merge and access instance variables do
not get recompiled when the class definition changes? That is strange that such a bug
still exists in Monticello. Try to do a very simple test case with a dummy package before
posting the bug on Pharo, I would like to check that.
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.
