Great, much appreciated -- a most excellent testcase! I can reproduce
the problem and have something that may work. Will finish this

I'm sorry for the late reply. Here is my small testcase:
I just add one line to call the end iterator of the last local row in the
built-in test case
*reinit_preconditioner_01.cc*under tests/petsc folder:
auto itr = mat.end(mat.local_range().second);
It produces the same error as I mentioned

The problem is that I still encounter the "out of range" problem even when I

Hi Wolfgang,
Fortunately, I managed to solve that problem. I found that every single
operation on the iterator needs to call row_length(), which
requires the assembled status of the matrix, and apparently set() operation
will break this status. My solution is to iterate and cache
the rows,
This time I used VectorOperation::insert and it didn't happen the memory error

OK, so that then clearly helps :-)

Hi Wolfgang,
This time I used VectorOperation::insert and it didn't happen the memory
error that I posted before.
However, if I put the compress function after the loop, it only sets one
entry on each rank then throws the exception
"Object is in wrong state, not for unassembled matrix."
