Because `vsnprintf` return value means: " The number of characters that would have been written if n had been sufficiently large, not counting the terminating null character. If an encoding error occurs, a negative number is returned. " `Logger` crashed when log msg was longer than LOGGER_BUFFER_SIZE. Checking `vsnprintf` return value solves this issue.
