Vectorisation Bug with sqrt

This code:

instruction_set = 'avx'
dtype = 'float32'
field_layout = 'fzyx'

config = ps.CreateKernelConfig(data_type=dtype,
                               cpu_vectorize_info={'instruction_set': instruction_set,
                                                   'assume_inner_stride_one': True,
                                                   'assume_aligned': False, 'nontemporal': False})

src_field = ps.Field.create_generic('pdfs', 2, dtype, index_dimensions=1, layout=field_layout, index_shape=(9,))

eq = [ps.Assignment(sp.Symbol("xi"), sum(src_field.center_vector)),
      ps.Assignment(sp.Symbol("xi_2"), sp.Symbol("xi") * sp.sqrt(src_field.center))]

ps.create_kernel(eq, config=config).compile()

produces:
