Valgrind still reachable errors

[shahes]

What is the proper way to destruct a global logger?

We get valgrind errors on program termination.

What is the proper way to destruct a global logger?

There isn't one. Global loggers are destroyed when global destructors are called. Valgrind generates its report at this stage too, which is why it may list those allocations. Ignore those records.
