Mikael's patch seems to do that trick as well as producing very nice assembly.

The equivalent C version of this test case ICEs with 4.4.4 but works with 4.3.5
and 4.5.0-RC-20100406.

Appears to have been fixed for 4.5 by r147566, see

I would like to add that changing
void printv_f32(const float32x4_t v)
into:
void printv_f32(float32x4_t v)
makes the problem go away, but the generated code is suboptimal.
