Reduced testcase:
enum eumtype { ENUM1, ENUM2 };
void g(const eumtype kind );
void f(long i);
void g(const eumtype kind)
{
  if ((kind != ENUM1) && (kind != ENUM2))
    f(kind);
}


--- the tree before VRP:
void g(eumtype) (kind)
{
  long int kind.0;

<bb 0>:
  if (kind_1 > 1) goto <L0>; else goto <L1>;

<L0>:;
  kind.0_2 = (long int) kind_1;
  f (kind.0_2);

<L1>:;
  return;

}
