Remove static initialization order dependency with SingletonHolder · 5883a29c

Martyn Gigg authored 6 years ago

Something changed in VS2017 such that SingletonHolder::once_flag
was not always initialized before SingletonHolder::instance and
this caused multiple singleton instances to be created. In some
ways this was a timebomb as static initialization order is
undefined.
