I think this is a bug fixed in subsequent versions. Already v.6.4.1 does not yield this message

Paolo
Thank you. I will upgrade my QE installation.

Sincerely yours,
M. Kondrin


          stopping ...

    The imput file is attached below. However, if I  change the
    coordinate
    of last atom to:

    C   0.500000000000000   0.875000000000000  0.777857142857143

    the job completes OK.

    Sincerely yours,
