            Bug ID: 32598
           Summary: SIGSEGV on recursive templates
           Product: clang
           Version: 4.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: vanyacpp at gmail.com

clang 4.0 crashes on this code:

template<class Predicate, typename T>
auto accept() -> decltype(Predicate::template requires<T>());

struct TypePredicate
        template<class T>
        static auto requires() -> decltype(accept<TypePredicate, T>());

void bar()
        accept<TypePredicate, int>();

Previous compiler versions correctly showed an error on this code.
