Bug #: 53405
Summary: Enum-dependent class template instantiations not
recognized
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ibugs@qult.net
The following code compiles with GCC 4.4.6, doesn't with GCC 4.5.4 and 4.6.0,
but does again with 4.7.0. I'm reporting this just in case the maintainers
aren't aware of it.
enum Tags { some_tag };
template <bool> struct BoolValue {};
template <Tags T>
struct Foo {
BoolValue<T == some_tag> meth();
};
template <Tags T>
BoolValue<T == some_tag> Foo<T>::meth() {}
The compiler complains about the return type of the method's definition being
BoolValue<(T == (Tags)0u)>
and not
BoolValue<(T == some_tag)>
which is clearly nonsense.
