Here's a slightly shorter testcase:

=========================================
struct A
{
  char c[13];
  int k[1];
};

struct A a[1];

void foo(int* p)
{
  int i, j;
  for (i=0; i<2; ++i)
    if (memcmp (a[i].k, p, j))
    {
      *p = a[i].k[0];
      bar ((struct A*) (a[i].k));
      break;
    }
}
=========================================

Btw, the error should be an internal_error and not a fatal_error IMHO:

flow.c:493:  fatal_error ("internal consistency failure");
flow.c:518:       fatal_error ("internal consistency failure");
flow.c:540:           fatal_error ("internal consistency failure");

We already have issue an ICE with the same message here:

emit-rtl.c:2239:      internal_error ("internal consistency failure");
