Ichthyostega de066348af Upgrade: workaround for compiler-bug ...

Compilation failure with GCC-14.2 with the following code

class Base
  {
  protected:
    Base() = default;
  };

struct Feed
  : Base
  { };

int
main (int, char**)
  {
    Feed f1;
//  Feed f2{};       /// does not compile with GCC 14.2
    return 0;
  }

In the actual code base this can be triggered when instantiating
classes with the `NonCopyable`-mix-in; seemingly the compiler attempts
to invoke the base class ctor directly, while it should invoke a
(synthesised) default ctor for the derived class.

The problem could not be reproduced with other compiler versions at Godbolt.org
