[petsc-users] VecGetSubVector causes NaN

If I use VecGetSubVector to get a subvector it works fine as far as I don't
destroy the original vector.
But, if I destroy the original vector, I get NaN values. So, it is my
misunderstanding of what the function suppose to do, or is it a problem?

I do the same thing with MatGetSubMatrix
and I haven't had any problem with it.
