G++ Bug with option -pedantic

Thanks for your bug report. I believe there is indeed an error in your
code.

This line reads

std::vector< T >::const_iterator src = other.begin() ;

Since std::vector<T> is a dependent name, const_iterator is taken as
an expression here. Since you want it to be a type, you have to write

typename std::vector< T >::const_iterator src = other.begin() ;

This error shows up with -pedantic only, because that disables the gcc
extension that typename is added implicitly in some places that would
be compile errors otherwise.
