Looks like it's caused by:

The problem is in getting vectype for f1_2:
foo (int b, double f1, double f2, int c1, int c2)
{
...
float D.1999;
float D.1998;
...
<bb 3>:
D.1998_3 = (float) f1_2(D);
REALPART_EXPR <u.cf> = D.1998_3;
D.1999_5 = (float) f2_4(D);
IMAGPART_EXPR <u.cf> = D.1999_5;
D.2012_10 = u.ci;
goto <bb 5>;
An immediate fix would be to replace the assert in
/* If op0 is an external or constant def use a vector type with
the same size as the output vector type. */
if (!vectype)
vectype = get_same_sized_vectype (TREE_TYPE (op0), vectype_out);
gcc_assert (vectype);
with 'return false', since get_same_sized_vectype currently just redirects to
get_vectype_for_scalar_type. But the comment (and the future intent) seems
incorrect for external defs, as f1 and f2 in this test.
