--- Comment #1 from Peter Bergner <bergner at gcc dot gnu.org> ---
Confirmed.  Here's a minimal test case.  It looks like the code for test1float1
is what is causing the problems.

typedef float vfloat1 __attribute__ ((__vector_size__ (1 * sizeof (float))));
__attribute__ ((noinline, noclone))
     vfloat1 test1float1 (float c)
{
  vfloat1 v = { c };
  return v;
}

void
test3float1 (void)
{
  float c = 17;
  int i;
  vfloat1 a = test1float1 (c);
  for (i = 0; i < 1; i++)
    if (a[i] != 17)
      __builtin_abort ();
}

int
main ()
{
  test3float1 ();
  return 0;
}
