is "uspp1_coulomb" the only test that shows a problem? if so,
you can safely use the code, except the rather peculiar case
of coulomb pseudopotentials (i.e. no pseudopotential but a
true coulomb 1/r potential, typically used for high-precision
calculations involving H atoms).

The case of coulomb pseudopotentials turned out to contain
some bugs, but it is hard to say whether they are involved
in your problem without more information
