Actually this is a well know bug in ifort 11.0
You can overcome this by 2 two ways
1: By upgrade your compiler to ifort 12
2: Modify your source code as below
INTEGER, PARAMETER, PUBLIC :: Byte = SELECTED_INT_KIND(1) ! Byte integer
INTEGER, PARAMETER, PUBLIC :: Short = SELECTED_INT_KIND(4) ! Short integer
INTEGER, PARAMETER, DIMENSION( N_IP_KINDS ), PRIVATE :: IP_KIND_TYPES = (/ SELECTED_INT_KIND(1),SELECTED_INT_KIND(4) /)
