Still accepts-invalid as of 4.2-20070430 (RC2).

If you're sure that it's a bug why isn't it fixed yet? Is it that hard that you
need more than six years?

Sure it's no show stopper but it's annoying. I'm using -pedantic and -ansi to
ensure platform independent code and then this...

gcc is a free software project driven largely by volunteers.  Interest in
fixing accepts-invalid bugs is generally low; people are generally more
interested in rejects-valid bugs, or in better optimizations, or in avoiding
regressions.  There are, unfortunately, many open bugs, many of which have
higher priority than this one.  If this bug is important to you, you do have
the option of fixing it yourself.

Ian, I know open source and I also know that some parts are more interesting
than others :-) 


Most the time I'm a happy GCC user (sure, it could be faster but that's what
compile farms are for). But this bug is assigned for nearly 6 years now that
makes me a bit sad.

"Other compilers have bugs" doesn't seem like a good reason to change GCC.

That's ancient, isn't it?

Yep, that is probably the better solution.

That is a question for the standards committee.

And the cases that are invalid were fixed by my patch.

Which?  Recent versions of EDG and clang both accept the testcase in comment
22.

> couldn't you at least give us a warning (e. g. with -pedantic)?

-pedantic means "strictly enforce the standard"; since the standard says that
the testcase in comment 22 is well-formed, -pedantic should not complain about
it.  Someone could add another warning flag to warn about this, but it isn't a
priority for me.

facts that
1) people don't write this intentionally
2) people expect this to be invalid (see number of duplicates)

No, that's valid. In the nested-name-specifier the second A only considers
namespaces, types and templates whose specializations are types
([basic.lookup.qual]) so it doesn't name the constructor.

Hi,

shouldn't

struct A
{
    struct B {};
};

int main()
{
    A::A::B b;
}

fail to compile? It compiles with 4.6 and 4.7.


Cheers,
André
