 This code is undefined as the address of a label will never be 128bytes, it
 will either be 4 or 8 bytes.

No, that would be

void *p = dummy;
memcpy (foo, p, sizeof (p));

Here, it's copying code from the address of the label.

Reduced testcase:
void jumpfunc(int copy, void *p)
{
__builtin_memcpy (p, dummy, 128);
 dummy: ;
}


This code is undefined as the address of a label will never be 128bytes, it
will either be 4 or 8 bytes.
