Here is a full testcase:
struct g{};
char y[3];
char *f = &y[0];
char *ff = &y[0];
void h(void)
{
struct g t;
*((struct g*)(f++)) = *((struct g*)(ff++));
*((struct g*)(f++)) = (struct g){};
t = *((struct g*)(ff++));
}
void abort (void);
int main(void)
{
h();
if (f != &y[2])
abort();
if (ff != &y[2])
abort();
}
