Synopsis: Adding new generic derivation of class with agent call on attribute causes execution seg fault

Description

A system has a generic class with a routine that constructs and calls an agent
on an attribute of the generic type G.  There is one generic derivation, with
actual generic DOUBLE.  A frozen system executes correctly.  But when a
new generic derivation (of a reference type) is added and the routine with the
agent is called and the system is melted, system execution ends with a 
seg fault.  Freezing the system then causes execution to produce the correct
result.

Added eweasel test incr344 for this bug.

To Reproduce

Run eweasel test incr344.
