WebbI think the rule was for before C++11: {/*..*/} was only use for aggregate initialization before C++11, so T{ data.data(), data.size() } could only store the future dangling pointer thus the diagnostic. With T(data.data(), data.size() ), it is a regular constructor call, so it actually depends of T constructor, so no diagnostic can be safely be done without … WebbA Computer Science portal for geeks.
