Error description

• Compiling a test case involving Fortran arrays and using the
  -qintsize=8 option is encountering an internal compiler error in
  the xlfhot compiler component.
  
  
     =====  TEST CASE  =====
  
    subroutine test( )
      real(4) :: a(0:6)
      real(4) :: b(3)
      real(4) :: c(2)
      real(4) :: d(2,2)
      integer :: l
  
      c(:) = MATMUL(d(:,:),b(1:2))
      l = minloc(a, MASK=a>1.0e-3, DIM=1)
  
    end subroutine test
  
  
  > xlf90_r -qintsize=8 -c test.F90
