SIGSEGV, segmentation fault occurred

I am running a graphene calculation, but keep getting the following error:
POSCAR found : 2 types and 26 ions
LDA part: xc-table for Ceperly-Alder, standard interpolation
POSCAR, INCAR and KPOINTS ok, starting setup
WARNING: wrap around errors must be expected

As suggested in some websites, it is maybe caused by memory limitation. So, I try a new simple model with only a single Fe atom, but still get a similar error as follows:
POSCAR found : 1 types and 1 ions
LDA part: xc-table for Ceperly-Alder, standard interpolation
POSCAR, INCAR and KPOINTS ok, starting setup
