It works (and is required to work) for other types, e.g.
[[gnu::noinline,gnu::noipa]]
int foo(void *p, void *q)
{
int n = 5;
int (*p2)[n] = p;
(*p2)[0] = 1;
bar(q);

Not that local types are never "merged" for cross-TU aliasing, they keep being
distinct types. In particular this applies to VLA types since the reference to
function-local vars ties them to the function
