ICE with integer parameter arguament

Using Intel(R) Visual Fortran Compiler 17.0.2.187 [IA-32] I have a number of ICE's the first one a have reduced to a simple case that replicates the problem:

module ice
    implicit none
    integer, parameter :: ld=82
    contains
    subroutine thingy
        character(ld)      :: gch
        integer            :: l1
        l1 =  unpad(gch,ld)
    end subroutine thingy
    function unpad(gbuf,ipad)
       integer             :: unpad
       integer, intent(in) :: ipad
       character(len=ipad) :: gbuf
       gbuf = adjustl(gbuf)
       unpad = len_trim(gbuf)
    end function unpad
end module ice

Configuration: Debug|Win32 ------

Compiling with Intel(R) Visual Fortran Compiler 17.0.2.187 [IA-32]...
Source1.f90
fortcom: Fatal: There has been an internal compiler error (C0000005).

The line that causes the ICE is "l1 = unpad(gch,ld)". If the parameter LD is defined in "thingy" rather than module ICE it compiles OK.
