-----------------------------------
Summary: Crash in RuntimeProfile::EventSequence::AddNewerEvents()
when events_ is empty
Key: IMPALA-6824
URL: https://issues.apache.org/jira/browse/IMPALA-6824
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 2.12.0
Reporter: Lars Volker
Assignee: Lars Volker
When {{events_}} is empty in runtime-profile-counters.h:347, events_.back() is
undefined. This can lead to a crash. The fix is to check for
{{events_.empty()}} before calling {{back()}}.
