--- Comment #5 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Better testcase:

// PR c++/70488
// { dg-do compile }

typedef __typeof__ (sizeof 0) size_t;
void* operator new (size_t, void *p) { return p; }
void* operator new[] (size_t, void *p) { return p; }

struct S { size_t s; };

void
fn (unsigned int s)
{
  char a[sizeof (S) + s];
  S *f = new (a) S;
  S *f2 = new (a) S [1];
}
