Bug?

[Carlo Wood]

Hmmpf. Almost always when I feel doubt it turns out I am wrong :(.
So I hestitate to send you anything that I didn't dig into myself
first for a while... but there is little digging into this :/.

Still I feel doubt though.  Is this a bug?  I appologise if it isn't.

>g++ -c 20000308.cc
20000308.cc: In method `A::A(const int (&)[4])':
20000308.cc:9: incompatible types in assignment of `const int[4]' to `int[4]'

>cat 20000308.cc
struct A {
  int a[4];
  A(int const (&b)[4]);
};

A::A(int const (&b)[4])
    /* : a(b) */	// (<-- gives same error)
{
  a = b;
}

The reason I think it is a bug, is because I'd expect the
complete array to be copied:

  for (int i = 0; i < 4; ++i)
    a[i] = b[i];

works fine, as does:

  memcpy(a, b, sizeof(a));

so why doesn't  a = b;  ?
