[Bug c++/11764] [DR147] g++ does not treat injected class name correctly.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11764 --- Comment #24 from André Wöbbeking Woebbeking at web dot de 2013-03-15 09:25:02 UTC --- OK, I read some explanations in the duplicates but still don't know why this should be valid code. IMO it makes no sense to write A:A:A:B and given the facts that 1) people don't write this intentionally 2) people expect this to be invalid (see number of duplicates) 3) some other compiler don't compile this couldn't you at least give us a warning (e. g. with -pedantic)?

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11764 --- Comment #25 from Jason Merrill jason at gcc dot gnu.org 2013-03-15 13:36:11 UTC --- (In reply to comment #24) OK, I read some explanations in the duplicates but still don't know why this should be valid code. That is a question for the standards committee. IMO it makes no sense to write A:A:A:B and given the facts that 1) people don't write this intentionally 2) people expect this to be invalid (see number of duplicates) And the cases that are invalid were fixed by my patch. 3) some other compiler don't compile this 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.

MSVC 2010 In another duplicate ICC 6 was mentioned. 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, Yep, that is probably the better solution.

Recent versions of EDG and clang both accept the testcase in comment 22. MSVC 2010 Other compilers have bugs doesn't seem like a good reason to change GCC. In another duplicate ICC 6 was mentioned. That's ancient, isn't it?

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

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.

But this bug is assigned for nearly 6 years now that makes me a bit sad. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11764

--- Comment #14 from ian at airs dot com 2009-05-30 16:03 --- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11764
