Hi all, I am implementing test cases to validate the implementation of my fixed_string class and basic_string_impl (based on flex_string) and noticed a defect in the implementation of: template< typename InputIterator > inline string_type & replace( iterator i1, iterator i2, InputIterator j1, InputIterator j2 ); It handles the Integral case fine, but when the InputIterators are actually iterators, it asserts false, where the standard dictates it returns: replace( i1, i2, basic_string( j1, j2 )); or equivalent behaviour, e.g. in the implementation I'm using: replace( i1, i2, std::distance( j1, j2 ), char_type()); std::copy( j1, j2, i1 ); Is there any specific reason for this, or is it an implementation bug?
