Okay, let's try in this way:

1) take my exmaple1

2) add to this example small class myPicture as you did with
FinishCreateSelf(). BTW, have you see that my VDK classes use virtual
inheritance from VVDK_Field. May be you have miss this point.

3) try to link.

If this reproduce problem, send to me project.

This stupid GCC start to make me angry! :-)
In CodeWarrior all this works just fine.
