There was a real bug with raw encoding but if you have
encoded wav files with 0.9 or earlier it is probably
safest to recode them to 1.0.

My hunch is that it's related either to the SSE or 3DNOW
asm routines.  I thought that the 3DNOW implementation
was turned off by default in 1.0 since I couldn't test
it myself.  SSE needs OS support to work and the patch
to determine support at runtime came after 1.0.  In 1.0,
I think it is turned off unless you pass a flag to
configure.
