Great, much appreciated -- a most excellent testcase! I can reproduce

Ben,
These two lines
added_sp.block(0, 1).copy_from(col);
added_sp.block(1, 0).copy_from(row);

These I can give back to you:

Dear Wolfgang,
thank you for your response. I will post the pull request on GitHub end of
this week, so that it can be reviewed. I will give a detailed reasoning for
each modification there.
