One compiler I need to use has problems with the following code:
---------------
#include <new.h>
class T {
public:
    T (int n) : _n (n) { }
    T (const T &ref) : _n (ref._n) { }
    ~T () { }

private:
    int _n;
};

void f ()
{
     T *ptr = new T [10] (1);  // line 14
}
---------------

In particular, it complains about the initializer to the vector new:
  CC: "test.cc", line 14: error: initializer for array of class object
			  created using `new' (1248)

Another compiler has no problems with the code, and the one giving the
error message has not proved to be reliable.  The question is: Is this
legal C++?  I read thru 5.3.4 from the april draft and as far as I
understood the code was flagged ill-formed.  Did I interpret the draft
correctly?  If I did, how am I supposed to allocate an array of
objects of class T?  With explicit calls to operator new and placement
new?

BTW, is either comp.lang.c++.moderated or comp.std.c++ archived
somewhere?  I recall I have read something about this matter some time
back.

As far as I know, comp.std.c++ is not archived anywhere.
(Any volunteers for this task...?)

I do have a record of all of the articles that I have
approved for comp.std.c++ (i.e. roughly 1/3 of the articles
since Aug 95); it is 338k gzipped, and since I happened to
have it lying around, I've made it available for downloading
at <http://www.cs.mu.oz.au/~fjh/comp.std.c++/posted.log.gz>.
