We come across what seems to be a bug in gcc. If a class F has a public zero
argument constructor, then we can declare a variable of type F::F, F::F::F,
etc. For example, the following source file:
// foo.cpp
class F {};
F::F::F::F::F f;
See: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11764
Still accepts-invalid with g++-4.3.2.
compiles with out errors in g++. The result is as if f is declared with
F f;
This is the case with the stock/latest GCC in Debian GNU/Linux x86_64
(v.4.1.2) and in Cygwin (v.3.4.4).
Is this the intended behavior?
No. :)
