17:00⎜«tobiasu» stellt sich trotzdem die frage warum memcpy das nicht auf die reihe bekommt
17:00⎜<mirabilos> du KANNST von “ptr” nur oldsize bytes lesen, nicht “size” bytes
17:01⎜<mirabilos> also gut, einfacheres beispiel
17:01⎜<mirabilos> ptr = malloc(PAGESZ);
17:01⎜<mirabilos> p2 = x_realloc(ptr, 2 * PAGESZ);
17:01⎜<mirabilos> versucht, 2 pages von adresse ptr nach adresse p2 zu kopieren
17:01⎜<mirabilos> aber die page hinter ptr ist ggf. nicht gemappt
17:01⎜<mirabilos> jetzt klar?
17:01⎜«tobiasu» lol, jau
