Line 4432 is this:  
  
  if (VOID_TYPE_P (TREE_TYPE (exp)))  
    {  
      /* C++ can generate ?: expressions with a throw expression in one  
	 branch and an rvalue in the other. Here, we resolve attempts to  
	 store the throw expression's nonexistent result.  */  
      if (want_value)  
	abort ();  
  
exp is a CALL_EXPR (calling _Jv_ThrowNullPointerException) inside a COND_EXPR.
