For testing, you're better off using decoder_example.c (it's
simpler) - but that's unlikely to actually cause significant
problems here.

We've hit a LOT of bugs with older versions of gcc in developing vorbis
(and in other compilers) - this is almost certainly the problem. Building
a cross-compiler is never all that much fun, but it shouldn't be too
hard. If it happens with a modern version (3.0.x preferred, but if you
have a reason to use something a bit older that should be ok - 2.95.2
works ok for vorbis on most platforms.)

If it still happens there, please do get back to us.

There's a good chance you'll hit problems later on, trying to decode
in real time (depending on how slow the chip is), but that can be
considered later on...
