I notice this should normally get initialised here (insert.c, instance() 
function)

    if (insno > csound->maxinsno) {
      size_t pcnt = (size_t) tp->opcode_info->perf_incnt;
      pcnt += (size_t) tp->opcode_info->perf_outcnt;
      pcnt = sizeof(OPCOD_IOBUFS) + sizeof(MYFLT*) * (pcnt << 1);
      ip->opcod_iobufs = (void*) mmalloc(csound, pcnt);
    }
