(POSIX and the C standards are explicit that employing memcpy () w ... ith overlapping areas produces undefined behavior.) Most notably, in glibc 2.13 a performance optimization of memcpy () on some platforms (inclu ... pied from src to dest . This change revealed breakages in a number of applications that performed copying with overlapping areas. Under the previous implementation, the order in which the bytes were copied had fortuitously hidden the bug, which was re ... ... 、さらには wcwidth (3) といったライブラリ関数は、 文字出力でどれだけカーソルが進んだか (0-2) を返す。 私用領域 (Private Use Areas; PUA) 基本多言語面 (Basic Multilingual Plane (BMP)) では、 0xe000 〜 0xf8ff の範囲は、規格ではいかなる文字も割り当てず、私 ... ... attack.
