I looked at the problem, but the current implementation is quite tricky.
I still have no satisfactory solution :-(
The main cause of the problem is that the packed storage of the strict
and unit lower triangular matrices is implemented as a lower triangular
matrix with one less row and column.
Please be patient for a few days more.
