[Csnd-dev] UDO problem in latest develop

The following UDO does not work with the latest develop sources. The print
statement shows that all four inputs argos are coming in at 0; If I revert
to the 7.0.0-beta.9 tag, it works fine.

opcode RissetHarmOsc(freq:i,ofs:k,amp:a,tbl:i):(a,a)
    koff1 = ofs
    koff2 = 2 * ofs
    koff3 = 3 * ofs
    koff4 = 4 * ofs

    printks(">> RissetHarmOsc ->%f %f %f %f\n", 5, freq, ofs, amp, tbl)

    ; a1 = poscil3(kamp, freq, tbl
    a2 = poscil3(amp, freq+koff1, tbl)
    a3 = poscil3(amp, freq+koff2, tbl)
    a4 = poscil3(amp, freq+koff3, tbl)
    a5 = poscil3(amp, freq+koff4, tbl)
    a6 = poscil3(amp, freq-koff1, tbl)
    a7 = poscil3(amp, freq-koff2, tbl)
    a8 = poscil3(amp, freq-koff3, tbl)
    a9 = poscil3(amp, freq-koff4, tbl)
    aL = a2+a4+a6+a8
    aR = a3+a5+a7+a9

    aoutL, aoutR = reverbsc(aL, aR, 0.4, 4000)
    xout(aoutL+aL, aoutR+aR)
    ; xout(aL, aR)
  endop

example calling statement:

a1L, a1R = RissetHarmOsc(icps,  0.004, aenv, giPrime)

Has something changed to make my UDO invalid in some way? I'm using this
code in as performance on Saturday and I'm focused on preparing, but I can
follow up with a minimal example.
