+++ This bug was initially created as a clone of Bug #884182 +++ Crash at android::OmxDecoder::ReadAudio() still happens even when Bug 884182 is fixed. STR 1. Browse http://people.mozilla.org/~cpeterson/videos/H264_Baseline_Profile_Level_30_640x360p.mp4 2. Touch home button 3. When home screen is shown, touch browser icon quickly. repeat 2. 3. forever very quickly until crash happens.
I found it, when I try to reproduce Bug 889167.

The crash happens when an interval of following function calls is too close. - nsBuiltinDecoder::SetDormantIfNecessary(true) - nsBuiltinDecoder::SetDormantIfNecessary(false) It it happens, nsBuiltinDecoderStateMachine's state change from DECODER_STATE_DORMANT to other state during freeing media resources.

This change bypasses the status check added in Bug 884182.
