            Bug ID: 70142
           Summary: Class members not in scope in exception-specification
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: barry.revzin at gmail dot com
  Target Milestone: ---

The following code fails to compile, with an error about y not being in scope:

struct X {
    X() noexcept(noexcept(y+1)) { }
    int y;
};

int main() { }

However, [basic.scope.class]/1 says that the scope of class members includes
exception-specifications.
