They're particularly bad when --enable-fully-dynamic-string is used, because even std::string().begin() will give a warning. Use pragmas to stop the troublesome warnings for copies done by std::char_traits. libstdc++-v3/ChangeLog: PR libstdc++/103332 PR libstdc++/102958 PR libstdc++/103483 * include/bits/char_traits.h: Suppress stringop and array-bounds warnings.
