I recently encountered this, and believe the issue is because the Out_CIF_STR() macro tries to get a Beq from each site and crashes since there is no standard beq.
I believe simply commenting out the lines dealing with Beq in the Out_CIF_STR() worked for me:
macro Out_CIF_STR_pdf(file, with_id)
{
out file
Out_String("\ndata_")
Out(Get(phase_name), "\n_chemical_name_mineral ?%s?")
Out(Get(a), "\n_cell_length_a %V")
Out(Get(b), "\n_cell_length_b %V")
Out(Get(c), "\n_cell_length_c %V")
Out(Get(al), "\n_cell_angle_alpha %V")
Out(Get(be), "\n_cell_angle_beta %V")
Out(Get(ga), "\n_cell_angle_gamma %V")
Out(Get(cell_volume), "\n_cell_volume %V")
Out(Get(sp_grp_char), "\n_symmetry_space_group_name_H-M %s")
Out_String("\nloop_")
#m_ifarg with_id ""
Out_String("\n\t_symmetry_equiv_pos_as_xyz")
Out(Get(sp_xyzs_txt), "%s")
#m_else
Out_String("\n\t_symmetry_equiv_pos_site_id\n\t_symmetry_equiv_pos_as_xyz")
Out(Get(sp_xyzs_txt_with_id), "%s")
#m_endif
Out_String("\nloop_")
Out_String("\n_atom_site_label")
Out_String("\n_atom_site_type_symbol")
Out_String("\n_atom_site_symmetry_multiplicity")
Out_String("\n_atom_site_fract_x")
Out_String("\n_atom_site_fract_y")
Out_String("\n_atom_site_fract_z")
Out_String("\n_atom_site_occupancy")
