| // The "basic_string" extern template instantiation declaration is supposed to |
| // suppress the implicit instantiation of non-inline member functions. Make sure |
| // that we suppress the implicit instantiation of non-inline member functions |
| // defined out-of-line. That we aren't instantiating the basic_string |
| // constructor when we shouldn't be. Such an instantiation forces the implicit |
| // instantiation of _S_construct<const char*>. Since _S_construct is a member |
| // template, it's instantiation is *not* suppressed (despite being in |
| // basic_string<char>), so we would emit it as a weak definition. |
