I think that it is a lot more likely that the snapshot we are using was
from a time before amr.c even existed in the ffmpeg tree.

Like I said before - someone decides to update the source, looks at all
the patches, updates the upstream copy, reapplies the patches.

This is *a lot* of work to get right, hence it doesn't happen regularly,
only when someone who understands it hacks on it.  Like I said before,
up to know this has only been Ronald.

I think your direction should be to fix the segfault you're seeing when
trying to follow Ronald's advice.  No point in swimming up stream.
