It renders fine here with 5.09.0. Nice piece by the way. :)

Hum.  That code is clearly wrong.  The table at p->t is longer that
the table passed and is repeated (wrapped) to make it easy to use.  I
suppose I am responsible for this code now, but it will take a little
time to remember what it is about!

The p->tlen is not the size of the array.  It is p->tlen+3-1 in
current code but should be p->tlen+4-1.  The base is p->t and is set
to be oscil_interp-1)/2 beyond; this is so interpolation is easier.  
The first loop fills the main table; the second fills the negative
value(s) and the third loop is supposed to fill the extra ones, so
should have body
       p->t[p->tlen+i] = p->t[i];
I think that the length in the csound->AuxAlloc call should be at
least 1 longer;  Probably should be (p->tlen + oscil_interp -
1)*sizeof(int32) but oscil_interp is 4 or less.


By the way, on my i386/floats there was no crash.

I fixed it this morning; in CVS now

Possibly I committed over; I was attempting to unify the two branches
I had and got to a stage of inconsistent CVS.
  Been looking at performance again -- going backwards I think!
