Sample code: std::wstring sInput = cca 20kB text (HTML template containing texts like "ImagePath1", "ImagePath2",...); std::wstring sFormat1 = cca 300kB text (base64 encoded image); boost::replace_all(sInput, L"ImagePath1", sFormat1); std::wstring sFormat2 = cca 300kB text (base64 encoded image); boost::replace_all(sInput, L"ImagePath2", sFormat2);

Do we need to fix it in Boost 1.61? Or it maybe already fixed?
