I just tried the following simple example:
#include <string.h>
struct S {
int i;
char c;
int j;
};
void f(void) {
struct S s1 = { 0, 0, 0 }, s2 = { 0, 0, 0 };
memcpy(&s1, &s2, 9);
}
int main(void) {
f();
return 0;
}
MSVC, Clang, and PC-Lint are all silent on the code (which is reasonable behavior since it's impossible to glean programmer intent from that snippet -- maybe the programmer really only wants the first nine bytes!). (Btw, yes, I am using the analyzer features for MSVC and Clang, not just relying on high warning levels.)
