I am working both with ABINIT 5.6.4 and ABINIT 5.8.3. For the structure given
below (see input file) the two versions of ABINIT give different k-points when
the automatic generation of the best k-point grid is selected. ABINIT 5.4.6
gives 6 and ABINIT 5.8.3 gives 14. Several OS have been tried (Windows/Vista,
Linux RH, OpenSuse, Fedora and 32bit vs 64bit).

Any ideas, explanations are more than welcome !
