More reduced testcase:
void baz (char *);
int c;
void
bar (void)
{
char a[2];
int *ip = c;
char *p = a, *q = (char *) ip;
const char *r = q + 2;
for (; q != r; p++, q++)
*p = *q;
baz (a);
}

Confirmed. Reduced testcase:

{
const char *r = q + 2;
for (; q != r; p++, q++)
*p = *q;
return p;
}
void bar(int *p)
{
char a[2];
