<pre>As confirmed by the resolution of Core Issue 244 (and dating back to C++98),
the lookup for the class-name "A" after the '~' below should be done in the
scope where the lookup for "AA" was done.
Since the lookup is performed prior to transformation into a class member
access expression (see 9.3.1 [class.mfct.non-static]), dual destructor lookup
(3.4.5 [basic.lookup.classref]) does not apply and the question raised in Core
Issue 399 does not arise.
A diagnostic is expected since ~A where the class-name resolves to M::A does
not name a member of N::A<int>.
Both GCC and EDG produce an error on this case.
### SOURCE:
$ cat nameADtor.cc
namespace N {
struct A { void selfDestruct(); };
}
namespace M {
typedef N::A AA;
union A;
}
void N::A::selfDestruct() {
::M::AA::~A();
}
### COMPILER INVOCATION AND OUTPUT:
$ clang -cc1 -Wall -Wextra -pedantic-errors -x c++ -std=c++03 nameADtor.cc
(No messages)
### EXPECTED BEHAVIOUR:
nameADtor.cc:11:14: error: expected the class name after '~' to name a
destructor
::M::AA::~A();
^
1 error generated.
