            Bug ID: 71035
           Summary: GNU does not give error on declaration of non literal
                    type in template function
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Judy.Ward at intel dot com
  Target Milestone: ---

Both EDG and Clang give an error on the code below.

GNU only gives an error if call() is not a template function (see -DERROR
below) or if call() is used in a way that requires it to be constexpr (i.e. in
a static_assert).

I think this should be an error.

struct C
{
   C(); // constructor is not declared constexpr
};

#ifdef ERROR
#else
template <class T>
#endif
constexpr void call()
{
   C c;
}

int main() {
#ifdef ERROR
   call();
#else
   call<int>();
#endif
   return 0;
}
