Comment #3 on issue 27856 by [email protected]: Crash -
MetricsService::RecordCurrentHistograms()
http://code.google.com/p/chromium/issues/detail?id=27856
This is a crash during shutdown (tail end of browser main, where at line
869 we try
to shut down metrics services), and hence it is likely that the user may
not notice
or be impacted.
That said, it appears that a snapshot of the list of histograms was taken,
but an
attempt to iterate over them identified a histogram that was deleted before
we got
around to iterating. Since histograms are USUALLY declared as statics, it
is
surprising to hear that one has been deleted (static destructor has
executed??),
before we have completed browser_main.
That said, there is a CL pending that will migrate us to use thread-safe
reference
counting to control the lifetime of histogram instances, and that should
make this
impossible(?) problem even less possible :-/.
I'm hoping to land this week.
