Creational Design Patterns in Modern C++ - Why a Double-Checked Locking Pattern (DCLP) Fails?

The video tutorial discusses the double checked locking pattern in multithreaded applications, highlighting potential issues due to compiler and CPU instruction reordering. It explains how these reorderings can lead to undefined behavior and crashes. The tutorial demonstrates debugging techniques to observe thread behavior and concludes with solutions using C-11 features for constructing a thread-safe Singleton.
