Here is the most reduced testcase I came up with (this might be another type mismatch problem in 
tree-ssa-phiopt but I could be wrong if you replace a1[0][i] by a[0][a==2] it works):
int g(void);
void h(int);
int a1[1][2]={{0,1}};
int main(void)
{
  int a = g();
  int i = (a==2)?1:0;
  h(a1[0][i]);
  return 0;
}
int g(void)
{
  return 2;
}
extern "C" void abort(void);
void h(int a)
{
  if (a!=1)
    abort ();
}
