| 6 | // that we suppress the implicit instantiation of non-inline member functions |

| 8 | // constructor when we shouldn't be. Such an instantiation forces the implicit |
| 9 | // instantiation of _S_construct<const char*>. Since _S_construct is a member |
| 10 | // template, it's instantiation is *not* suppressed (despite being in |
| 11 | // basic_string<char>), so we would emit it as a weak definition. |
