Bug ID: 20570
Summary: clang C++ partial specialization of nested template
(reject valid)
Product: clang
Version: 3.4
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Bug appears when you try to specialize template within another template.
Minimal snippet:
=============================
template <class>
struct Foo
{
template <class>
struct Bar;
};
template <class T>
template <>
struct Foo<T>::Bar<int>
{};
=============================
However, if you add an one additional (undeductional) parameter in the
specialization, the code is compiled. "template <class>" instead of "template
<>".
Minimal snippet (is working):
=============================
template <class>
struct Foo
{
template <class>
struct Bar;
};
template <class T>
template <class>
struct Foo<T>::Bar<int>
{};
=============================
