Log application got coredump due to failed assertion in Log agent.
The problem was caused by referring to uninitialized variable `bool updated`.
Previously, `updated` variable was initialized when the method
`FetchAndIncreaseRefCounter` or `FetchAndDecreaseRefCounter` was called.
The value of `updated` is true, means the reference counter has been updated,
false otherwise. So, if `updated` variable was unluckily assigned `true`
in default, reference counter could be restored unexpectedly.
