Copy constructor access check while initializing a reference

["Peter A. Felvegi" <petschy at praire-chicken dot com>]

hello,

i've found this in the known non-bugs list
(http://gcc.gnu.org/bugs.html#known), after running into the issue. gcc
3.4-4.2 gives a compile error, but 4.3 compiles it. is this a
regression, or the rules were relaxed somewhat (c++0x?) ? i checked the
changelog, but couldn't find any relevant entries there.

could someone explain the rationale behind this extra access check,
please? i'm puzzled, since the copy ctor is not needed and is not called
from the generated code.

regards, p
