Hi,

I'm having a problem in hybrid-type calculation. I have a NiO slab, and I set

LHFCALC = .TRUE.
HFSCREEN = 0.2
AEXX = 0.25

ISPIN = 2

It gives a segmentation fault and stops after 4 iterations. I don't think it's a memory issue since my unit cell is only 4 atoms. It works fine for the bulk NiO. Is hybrid functional not suitable for slab calculations?

Thanks.
