Hey all,

Can anyone explain this bug?

I use the 'ispecwp' option in pvoc set to non-zero, and when I start to
compile my .csd, this error is spit out:

<snipped to get to interesting bits>

tidy up: Aborted


I'd really like to preserve the spectral 'envelope' with the ispecwp option,
but it's not cooperating with my wises!

Help!?
