[petsc-users] Destroy ghosted vector that was used to duplicate

[John Mousel]

Is it legal to destroy a ghosted vector if it has been used in VecDuplicate?

Something like:

VecCreateGhost(...,vec1)
VecDuplicate(vec1,vec2)
VecDuplicate(vec1,vec3)
VecDestroy(vec1)
VecAXPY(vec2,1.0,vec3)

Is this legal or are the scatters left hanging in the ether?
