Figured it out. I needed to insert instructions to set and restore
VRSAVE around my code.
The Apple VE website implies that this is handled automatically by the
compiler. Clearly it isn't.
cheers,

Hi,
I'm having a weird problem with my AU render, which makes heavy use of
Altivec.
On a debug build all is well. However on an optimised build, the sound
cuts out completely after a short while. Looking in the debugger, it
looks as though all my Altivec registers have suddenly taken the value
0x7fffdead7fffdead7fffdead7fffdead.
Anyone got any ideas? The only thing I can think is that the register
file is getting hit by an interrupt, but I don't know why that would
only happen on an optimised build.
cheers,
os.
