g++-4.3 rejects the following code:
namespace n1 {
struct foo{};
}
namespace n2 {
struct foo{};
}
using namespace n1;
using namespace n2;
template <typename tp>
int run(tp const & t) {
return t.foo;
}
struct bar {
int foo;
};
int main() {
bar b;
run(b);
}
the error message is:
bug.cpp: In function âint run(const tp&)â:
bug.cpp:14: error: reference to âfooâ is ambiguous
bug.cpp:6: error: candidates are: struct n2::foo
bug.cpp:2: error: struct n1::foo
g++-4.1 and g++-4.2 accept the code, though ...

Caused by my http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=129836
This is during tentative parse, so I guess the errors should be suppressed.

This is worse than PR32384, so either we have a fix for it or we should revert
the fix for PR32384 before 4.3.0.

------- Comment #6 from jakub at gcc dot gnu dot org 2008-02-11 23:11 -------
cp_parser_class_name since PR20293 errors unconditionally even during tentative
parse. Mark, is there a way to get a silent tentative parse of the optional
nested name specifier plus typename? Or is trying to parse it tentatively
as pseudo-dtor followed by parsing it as id-expression/member access if the
former just never going to work?
