[PD-dev] using rand() in an external

[Greg Surges]

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
