            Bug ID: 16273
           Summary: this->f<T>() in trailing return type gives
                    lib/Sema/SemaTemplate.cpp:260: Assertion failed:
                    "Caller should have completed object type"
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW

Testcase reduced from bug 16243 comment 4:

struct A {
  template<int N> void f();
  auto g() -> decltype(this->f<0>());
};

gives:

lib/Sema/SemaTemplate.cpp:260: void
clang::Sema::LookupTemplateName(clang::LookupResult &, clang::Scope *,
clang::CXXScopeSpec &, clang::QualType, bool, bool &): Assertion `(isDependent
|| !ObjectType->isIncompleteType()) && "Caller should have completed object
type"' failed.
