But this "derivative" (if you assume that it is a derived work) is created by the user on their home computer, and is not redistributed. Since it's not "distributed or published", it's not subject to the GPL's 'viral' requirements under section 2b:

>b)  You must cause any work that you distribute or publish, that in

(Emphasis mine)

This is why the runtime in-memory state of the dynamically linked code is not directly relevant to the GPL's 'virality'.
