--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Reduced to a single file:

struct B {
  B() { throw 1; }
};

B f() { return B(); }

struct S {
  B b = f();
};

int main()
{
  try {
    S s;
  } catch(int) {
  }
}


In __cxa_throw we return from _Unwind_RaiseException and run:

82        // Some sort of unwinding error.  Note that terminate is a handler.
83        __cxa_begin_catch (&header->exc.unwindHeader);
84        std::terminate ();
85      }
