Note here is the reduced C testcase which shows that this is not PHI-OPT bug as 
PHI-OPT does nothing:
int g(void);
void h(int);
int a1[2]={0,1};
int main(void)
{
  int a = g();
  _Bool i = a==2;
  h(a1[i]);
  return 0;
}
int g(void)
{
  return 2;
}
extern void abort(void);
void h(int a)
{
  if (a!=1)
    abort ();
}
