| ## A DW_TAG_GNU_template_parameter_pack with three identical |
| ## DW_TAG_template_type_parameter children (all referring to the same |
| ## int base type) must be preserved as three separate child DIEs after |
| ## linking. Before the parallel linker registered the pack tag with |
| ## SyntheticTypeNameBuilder, pack children received no ordered synthetic |
| ## key and TypePool deduplicated the three siblings down to one. |
