I believe I have incurred this same bug on gcc 4.7.2 with copy constructor, and
both move & copy assignment operators.
A workaround for my case is to have only the function declaration inline, and
to move the defaulted declaration out of line. Keeping everything else the same
- extern template declaration, explicit template instantiation, and file layout
- this yields the required results.
