This is not a bug. cyclic_size is deliberately fixed at 4, because in some cases even on 64-bit systems you only get 32-bit leaks. You can still change it manually if you for some reason need payloads longer than 456976 bytes.

Can you please elaborate?

For example, on amd64 most of the instructions operating on 32-bit numbers are shorter than their full 64-bit counterparts, and therefore preferred by compilers when upper 32 bits are not relevant; and before the value gets to the place of use, it might undergo such clobbering. Thank you for taking the time to report this.
