Giving GCC 4.4.3 the following code with the arguments "-O1 -mcpu=cortex-a8
-mfpu=neon -mfloat-abi=softfp": 

############################################################

#include <stdio.h>
#include <arm_neon.h>

void printv_f32(const float32x4_t &v)
{
        printf("%f\n", vgetq_lane_f32(v, 0));
}

int main()
{
        float32x4_t v = {0.0, 1.0f, 2.0f, 3.0f};

        printv_f32(v);

        return 0;
}

Results into an ICE:
