Sorry everyone, one major flaw in my proof:

I was still sending it the raw data, but in a loop so it was doing the
whole broken record thing. that tipped me off, looked back, figured it

<p>The bug has nothing to do with libshout I think, maybe, but it's more
probobal with libvorbis.  The reason it was not crashing with strait up
data but was segfaulting with page-aligned data was not because it was
page-aligned but because I was also changing the serial number.. with
the first stream being # 0.

Apparently, if I bump the initial serialno to 1 it works great.
