You are passing a maxmem of 2**25, which is 33554432 bytes. Setting n=32768, r=8, p=16 causes it to compute a Blen = p * 128 * r = 16384 and a Vlen = 32 * r * (n + 2) * 4 = 33556480. 33556480 + 16384 = 33572864. Since that is larger than 2**25 it fails. Raise the maxmem limit and this failure will go away.
