Right. I never designed Memory to be copied. Since it, internally, uses a
scalar datatype, the default copy does a copy of double[] not double_v[]. Feel
free to report such issues directly on the bug tracker. I created one now:
http://code.compeng.uni-frankfurt.de/issues/618
Thanks for the investigation and report.
Cheers,
Matthias
