The code you have posted looks fine as far as I can tell, so if there is a
memory leak then I think the problem is elsewhere. I suspect that the
TelemetryProtobuf::EventName proto passed to PopulateEventName() is not
getting destroyed. Or if you're using an arena, then the arena that proto
was allocated on is not getting destroyed.
