Stroustrup, The C++ Programming Language, Section r.5.3.3, pg 499.

" No initializers can be specified for arrays.  Arrays of objects of a
class with constructors can be created by operator new only if the class
has a default constructor(r.12.1).  In that case, the default constructor
will be called for each element of the array."

i.e. what you did with the int there wasn't correct C++ at the time the
book was written.  Granted this reference was current May 1991 so there's
plenty of time for it to change.  Still I'd be checking that what you're
trying to do is legal.
