renumberMesh crashes when lengthScale is cubeRootVol

[timofeymukha]

When lengthScale is set to cubeRootVol (whichis the default), the utility renumberMesh will crash with

--> FOAM FATAL ERROR: (openfoam-2306)
unallocated autoPtr of type N4Foam5FieldIdEE

    From T& Foam::autoPtr<T>::operator*() [with T = Foam::Field<double>]
    in file /home/timofey/code/openfoam/OpenFOAM-v2306/src/OpenFOAM/lnInclude/autoPtrI.H at line 95.

Very strange bug, the crash seems to happen due to the function

void Foam::SingleCellSampler::createLengthListCubeRootVol()
{
    // Cell volumes
    const scalarField & V = mesh_.V();
    
    forAll(lengthList_, i)
    {
        lengthList_[i] = pow(V[indexList_[i]], 1.0/3.0);
    }
}

particularly due to the mesh_.V();. If one removes any mention of mesh_V() things work... I have no idea what is happening.

Setting lengthScale to WallNormalDistance works fine, even though that also uses the mesh class, even more extensively in fact.
