Vorbis dev - Jan 2014 - Tremor crash on armel

Hi,

Debian Project News drew my attention to an RFH 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698378 for a crash in 
libvorbisidec (tremor) on ARM systems.

I have been in contact with Daniel Kahn Gillmor proposing to try to help 
solve this crash on armel.
Unfortunately Daniel hasn't been able to reproduce it recently.

Can anyone shed any light on this crash or on how to reproduce it, please?
(Or on any other bug with which you would like help.)

I am a newbie on this list so here is some personal inormation:
- I am an experienced C programmer but I am (nearly) retired and I am 
looking for a way to help the community and to keep my remaining neurons 
active.
- I am not particularly familiar with Vorbis but I have optimized 
JPEG-like decompression which also uses DCT and Huffman encoding.
- I am familiar with bitstream handling as I have worked for about 18 
years extracting data from satellite telemetry.
- I have several armel systems running (oldish versions of) Debian 
either natively or in a chroot (plus, of course, i386 and amd64 ones).

TIA.

Cheers,
Chris

Hi Chris. I don't know anything about the crash he mentions, but the
first step with any crash bug is reproduction. Maybe try running all the
vorbis files you can find through mpd?

Tremor is distributed with Firefox on Android and Firefox OS, so the
code is getting active testing; I haven't seen any crash bugs from that
deployment. Maybe it's an interaction bug, or requires a particular
input file. ...Or only happens with old versions.

We could certainly use more folks to help with maintenance. Welcome to
the list! Did you watch the Rosetta spacecraft wakeup signal?
