When a thread terminates, objects pointed to by Thread Specific Pointers (TSPs), also known as Thread Local Storage (TLS), are deleted. One of these thread-local objects is used for logging. If the logging TSP is deleted before another TSP and the later TSP tries to log anything in its destructor, this can cause a segfault.

The code should be modified to guarantee that the TSP used for logging is the last TSP to be deleted so that other thread-local objects can use the logging system during object destruction.
