--- Comment #1 from Chris Uzdavinis <cuzdav at gmail dot com> ---
I get a similar warning with this code. Unsure if it's the same underlying
issue. Also does not warn with g++10 or g++11, but does with newer versions.
#include <sstream>
#include <string>
std::string create() {
std::ostringstream oss;
return oss.str();
}
