This one runs the problematic code, but since this is a compile-only test, it
can't detect a problem. A variant that does fail:

extern void abort (void);

int                     f(void) { return 2; }
unsigned int            g(void) { return 5; }
unsigned int            h = 1;

typedef unsigned int vec __attribute__((vector_size(16)));

vec i = { 1, 2, 3, 4};

vec fv1(void) { return i + (h ? f() : g()); }
vec fv2(void) { return (h ? f() : g()) + i; }

int main(){
  vec j = fv1();
  if (j[0] != 3) abort();
}

(it works ok with fv2)
