| Michael et. al. --
| 
| G++ 1.35.0 on a uvax3.
| 
| Consider the following program:
| 
| --------------------------------------------------
| #include 
| 
| struct foo {
|  public:
|   foo();
|  private:
|   int i;
| };
| 
| foo::foo() { cout << "Hello.\n"; }
| 
| void main() {
|   foo f(7);
| }
| --------------------------------------------------
| 
| This should give an error message, because there is no "foo"
| constructor that takes an integer argument.  Instead if gives no
| argument.  Even more insidious, it does not call the default
| constructor -- when run, the above program prints nothing.
| 
| Thanks.  Ad astra.
|
