            Bug ID: 45142
           Summary: Segfault from pseudodestructor with template alias
           Product: clang
           Version: 9.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: ndkrempel at gmail.com

I don't have a view on whether the following code is valid C++ or not, but it
is segfaulting clang:

template <typename T> using Alias = int;
int main() {
    (1).template ~Alias<int>();
}

(Compile error in 8.0.0, segfault in 9.0.0 up.)
