   This particular bug was because ihigh is the maximum 32 bit integer
2147483647 so multiplying it by the integer item size (4) caused
overflow. Adding an extra check fixes this:
    if (ihigh > self->lengthBody / self->itemSize)
        ihigh = self->lengthBody / self->itemSize;

   Committed a new version 1.02 and new downloads are available from
Google code.
