The issue was, that we don't pass evsel pointer into symbol__annotate() function, which got over looked in the last annotation changes. [1] https://marc.info/?l=linux-kernel&m=151060884412702&w=2 Committer note: This fixes the crash, but makes it stumble into another bug, double locking the annotation data structures, that is in turn fixed by the next patch in this series.
