--- Comment #5 from Anton <bikineev at google dot com> --- Looking at the COMDAT groups for the example with 2 instantiations (Index<int> and Index<float>), I think this is what is actually expected: section for Index<int> must not be grouped with section for Index<float>. In general, different instantiations must be kept in different COMDAT groups. Otherwise, it would not work e.g. if one TU instantiates Index<int>, the other TU instantiates Index<int> and Index<float>.
