ug. This looks like a defect in the std. As has been pointed out, we cannot
parse the default argument until the outer class is complete -- because the
default argument of the nested class can legitimately c

Dear Giovanni Bajo,
Thank you for that detailed explanation. Based on what you said, it sounds
like a complex problem to solve; however, it may not be as difficult as it
first appears. Take the example belo

I would like to thank you folks at gcc.gnu.org for taking a serious look at
this issue.
I wanted to write here a little bit about what I do and how this matter came
to light. It is my occupation to write cr

Of course I meant "classes": "There is some code which also delays inner

I can't find anything in the standard which says that this should be an error,
regardless of what Comeau does. This looks like a genuine bug in the parser,
see parser.c:cp_parser_class_specifier: the parsin

I'm sorry, but I have no idea what you mean by that. If you want to say
that O::B is instantiated by O::D, which is still inside O, yes, of
course that's the case. And I'm happy if the default arguments aren't

This code is still invalid, B is instantiated while in the class which
means that the default
argument is not going to be parsed at all. ICC and Comeau give the same error.
Now the off by one

In private mail, I got another testcase that is even weirder:
---
struct O {
template struct B {
void set (T, bool=true);
};
struct D : public B {};
};

The error comes from:
tree

{
/* If the ARG is an unparsed default argument expression, the
conversion cannot be performed. */

Here's the same testcase again, but shorter:
---
struct O {
template struct B {
void set (T, bool=true);
};
struct D : public B {};
};
void x ()

This is invalid code and the error is correct. The default argument has not
been parsed at the point you
called it.
ICC and Comeau gives a slightly different error message which I think is
misleading:
