Responsible Changed From-To: freebsd-alpha->freebsd-bugs This is not an Alpha-specific bug but happens on all LP64 platforms such as sparc64 and ia64 in current as well as alpha. Responsible Changed From-To: freebsd-bugs->fanf I'm dealing with this. State Changed From-To: open->patched I've committed the bignum Pollard Rho factor(6) from NetBSD to -CURRENT State Changed From-To: patched->closed All the new hotness has been MFCed. |
when using ``factor'' on the alpha platform it gives a wrong result when someone tries to factor numbers > 4294967295 that contain of factors that are >= 65539. $ factor $(echo "65539*65539" | bc -q) 4295360521: 4295360521 ^^^^^^^^^^ wrong. Fix: i think its not easy to fix without modifying /usr/src/games/primes/pr_tbl.c How-To-Repeat: $ factor 4295360521
