The projector augmented wave (PAW) formalism of Blöchl [PRB 50 1795 (1994)] has been implemented in a number of electronic structure code packages and generally has become an important tool for density functional simulations of materials. However, occasionally unphysical results are generated. A source for such occasional anomalous behavior is traced to one contribution present in some codes that use the reformulation of the exchange-correlationterms introduced by Kresse et al. [PRB 59 1758 (1999)]. A remedy is discussed which has been implemented in new versions of the atomic dataset generation program ATOMPAW [CPC 135 329 (2001)].
