<pre>test.cpp:
template <typename T>
struct C {
template<typename U>
void Get() {}
};
template <typename T>
class A {
using C<T>::Get;
void Run() { Get<int>(); }
};
Compiler invocation:
clang test.cpp:
clang/lib/Sema/SemaDecl.cpp
1064 TemplateDecl *TD
1065 = cast<TemplateDecl>((*Result.begin())->getUnderlyingDecl());
1066 IsFunctionTemplate = isa<FunctionTemplateDecl>(TD);
1067 IsVarTemplate = isa<VarTemplateDecl>(TD);
On line 1065, the underlying Decl was expected to be a TemplateDecl. With the
code provided above, the actual Decl returned was a UnresolvedUsingValueDecl,
leading to an assertion failure inside the cast call.</pre>
