Andrew Peter Marlow commented on AVRO-4248:
-------------------------------------------
This looks potentially serious. Have you been able to get any idea on the kind
of impact it might have? A standalone program that crashes due to the error
would be nice to see, otherwise it get get dismissed as something that is only
seen when the sanitizer is used.
