Excellent, worked like a charm. I had an uninitialized outlet pointer. *grin*

Thanks much for the gdb tip, I'm certain it will come in handy often.

Crashes are usually because memory hasn't been allocated properly.  I'd check x->current and x->step.  Hooking up to gdb will give you a lot more info.  Search puredata.info for 'gdb' for a little howto.

Hi all,

The following code crashes Pd when the randomwalk object receives a bang...
I'm stuck as to why, can anyone see a reason?
void randomwalk_bang(t_randomwalk *x)
{
    t_float randval = rand() % 2;
    if(randval == 0) randval = -1;
    if(randval == 1) randval = 1;
    x->current += (x->step * randval);
    outlet_float(x->f_out, x->current);
}

Thanks in advance,

-Greg
