Resolution: invalid
Status: assignedclosed

This is expected behavior. Copy operation of returned object make copy of string and copy of cursor. String is new object, but cursor point to original string object. Original string object is finalized after the copy and invalidates all cursors which point to it.

To aviod this you can declare String_Source as limited type or make it controlled and provide own Assign operation.
