Paul,
Thanks for your help. Basically the issue was that the process()
callback could get called before Hydrogen's audio engine was completely
initialized. For some reason the H2 developers could not reproduce the
crash.
The bugs (there were actually two) are now fixed, one by Comix, one by
myself. Everyone who was hitting this, please try H2 CVS.

so, the port buffer pointer was null. going further down the stack:

i'm suprised to see that the "arg" is null.
sampleRate = 1.17287768e-35
odd, though possibly OK.
