There are some further questions though.
E.g. address_compare has a smart code to assume that static vars will never be
adjacent to automatic vars or vice versa (the implementation guarantees that):

So, for #c5,
if (&a[1] == &b[0])
instead of if (a+1 == b+0) works right, that is handled by the match.pd
(cmp (convert1?@2 addr@0) (convert2? addr@1))
address_compare simplification. And it also works f

{
int a[] = { 1, 2 };
int b[] = { 3, 4 };
