error message with "irep(...)" for function with template type arg

[Mark Aagaard]

The program below gives an error message that begins with "irep(...".  

The programs compiles with g++.  If replace the template type with `bool`, the program passes cbmc.

I'm using cbmc 6.8.0 on ubuntu 22.04.

Program:

```

template <typename T>
class vector {
  private:
    T*             _data;        

  public:
    vector( unsigned short num ) {
      _data = new T[ num ];
    }
};


template <typename T>
void buggy_rot( vector<T> xv )
{
}

int main()
{
  vector<bool> xv0 = vector<bool>( 10 );
  buggy_rot( xv0);
  return 0;
}

```

Error message:

```
