Follow-up Comment #4, bug #60928 (project octave):
It will take some time to check, but I think you are on the right track. The
Octave project began a long, long time ago before many parts of C++ had been
firmed up. Relevant to this, Octave was coded before move constructors even
existed--everything was a copy constructor. My guess is that it would be
possible to improve this by figuring out how not to create new arrays which
involves a lot of memory allocation and copying of values.
