--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Cleaned up testcase which still ICEs with -O2 on the current trunk:
struct S { int a[1]; };
__thread struct T { int c; } e;
int f;
void bar (int);

void
foo (int f, int x)
{
  struct S *h = (struct S *) &e.c;
  for (;;)
    {
      int *a = h->a, i;
      for (i = x; i; i--)
        bar (a[f]);
      bar (a[f]);
    }
}
