Description

[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

This bug was filed from the Socorro interface and is 
report bp-798d715d-48da-4dc8-8ac8-80ff72140606.
=============================================================


Unable to find STR for this crash. I was in the browser at this website: http://mozilla.github.io/qa-testcase-data/webapi/mediarecorder/index.html running a few test cases for Media Recording API, then let the phone idle and then the phone crashed. No other apps were open.

Hi Randell, here's a webrtc crash bug.

Comment 2

[Randell Jesup [:jesup] (needinfo me)]

Really appears to be in http://hg.mozilla.org/mozilla-central/annotate/c8288d0c7a15/media/webrtc/trunk/webrtc/modules/utility/source/process_thread_impl.cc#l159 - the link to sigslot.h seems totally bogus.

The source line is:        CriticalSectionScoped lock(_critSectModules); 

Perhaps nothing removed it from the list of periodic Process() events before deleting it.

We've made multiple attempts to find STR here, but we're not successful. If we get new information that could imply a hint of STR here, then let's re-add the QA keyword.
