This bug was filed from the Socorro interface and is 
report bp-4566f943-5c4f-4381-b4fd-20e272150211.
=============================================================
Environment:
Device: Asus Transformer TF101 (Android 4.0.3);
Build: Firefox for Android 38.0a1 (2015-02-10);

Steps to reproduce:
1. Go to http://mozilla.github.com/webrtc-landing/gum_test.html;
2. Tap on 'Audio & Video';
3. Choose 'Share'.

Notes: Probably device specific, since I am not able to reproduce this on other devices.

Seems actionable. There are a good number of tft101s floating around Mozilla.

Snorp said in triage that this is Neon code being called on a device that does not support neon (Tegra 2).
Upstream bug:
https://dxr.mozilla.org/mozilla-central/source/media/webrtc/trunk/webrtc/modules/audio_processing/aec/aec_rdft.c?from=aec_rdft.c&case=true#583

This is missing a check for NEON. aec_rdft_init_neon unconditionally replaces the routines.
But wait, there's more:

Instead of a try run I will offer one Belgian beer to the relevant sheriff if this goes red on m-i.
