Hi,

I found, some times ago, that the implementation of the LibXC was not 
compatible with the SCF mixing on the density, which is the default using 
PAW. I don't know why; one should ask to the person who implemented the libXC 
in Abinit.
If you use PAW (apparently yes; pawecutdg is present in your file), try using 
a SCF mixing on the potential: select iscf=7 instead of the default 17.

Objet : [abinit-forum] ABINIT BUG using ixc > 26 or any of ETSF LibXC 
functionals
 
ABINIT reports a bug when I am trying functionals with an ixc number larger
than 26 or the ETSF ones from ETSF Lib XC. Below I am giving the input file I
am using.
