(g:2c3d487a9a8af00c0c462cd4e1a112804b9cc156) ICEs when compiling the following
testcase, reduced from f18/testsuite/Semantics/data04.f90 from the flang 11.0.0

module at
contains
subroutine r8(zd)
type uk
integer, allocatable :: h5(:)
end type uk
type(uk) :: n0
integer :: zd
DATA(n0 % h5(zd), zd = 1, 10) / 10 * 1/
