[Wien] Fe(111) surface - LAPW0 error

Dear Yiyang,

well, the "segmentation error" tells almost everything...

what are your shell limits?
in csh-like environments: limit
in sh-like environments: ulimit -a

you need to set memory and stack to unlimited. If it still does not 
help, you should probably add memory or swap space.

Best regards,
Torsten Andersen.
