That doesn't make this valid; you're violating the One Definition
Rule.  The problem is that a single virtual table for class X is
generated.  You may fix your program by defining class X in unnamed
namespaces; this will ensure that the different definitions are not
mixed up.

namespace {
  class X { /* ... */ };
}
