From the QByteArray::constData's documentation: "The pointer remains valid as long as the byte array isn't reallocated or destroyed.". If you don't store the QByteArray into a variable, the temporary is destroyed immediately. > And why only the content is wrong? Because you were lucky. It is not allowed to access memory in such a way in C++.
