The line that crashes is
https://github.com/apache/impala/blob/b39cd79ae84c415e0aebec2c2b4d7690d2a0cc7a/be/src/runtime/query-state.cc#L1033
My guess is that inside the actual segfault is within WaitForPrepare() but it
was inlined. Not sure if a remote filter can arrive even before
QueryState::Init is finished - that would explain the issue, as
instances_prepared_barrier_ is not yet created at that point.
