This test was what was suggested to me.
I redid the test, now specifying --param ggc-min-heapsize=2000000,
in order to effectively disable GC.
Now the reported numbers for memory allocated (298) and used (296) are 
identical,
only the reported overhead is 4k less for the version with extra 
fields, indicating
more data is stored.

What test would you propose that would be able to show any increase
in memory usage?

At this point it is really hard for me to see extra memory use as a
reason to use another approach.
