Crash at RDS onConfigUpdate #3953
Description
Description:
Please see crash backtrace in https://github.com/istio/proxy/issues/1877
It crashed at this line:
envoy/source/common/router/rds_impl.cc
Line 100 in c92a301
factory_context_ is gone. One possible cause is this RdsRouteConfigProvider is created by one ListenerImpl which is stored as factory_context_ in the provider. But this provider is shared by the second ListenerImpl since provider_manager is singleton or global. The first ListenerImpl object maybe gone when the provider::onConfigUpdate is called.
Repro steps: None
