OK - I guess that we need class_pointer/class_target/class_allocatable attributes that are retained by the symbol, rather than the container. Cheers Paul PS I have to recover the steps between the last unlimited polymorphic patch that I sent you and the present on, which does the job for unlimited OOP but breaks something such that regressions run into the hundreds. I have stared at it for a couple of evenings but cannot see what generates the problem. If I do not see it by Sunday, I'll let you take a look.
