This patch fixes errors reported by GCC’s undefined behaviour sanitizer about calling functions with a null pointer: ./configure CC="gcc -fsanitize=undefined" Using Issue 22605 as a precedent, I propose to avoid calling memcpy() and memmove() for zero-length copies when there may be a null pointer.
