Not entirely the same. The problem isn't the polynomial, but the entire model.
crcutil also has many fatal flaws for inclusion in other projects: the code is horrifically ugly, it's hosted on google code so it looks unmaintained and abandoned, it's C++, it uses unreadable ASM to be "fast" but that's not portable across all the architectures Redis runs on, and it has a horrible build system (because of ASM and C++ and other issues).
