Thank you for assistance! That seems to be output from an older version (before rev. 9) of the program. How get you the code? I tried bzr branch lp:primes/ from a clean place, built via make, run it as
./primes64 7757777773 7757777787 and it prints: start=7757777773, stop=7757777787, mode=0x0, loglevel=1 totally 0 primes, last one is 7757777773 sum is 0 + 2^64 * 0 Or maybe you built it in some unusual environment, like mingw? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/725367 Title: primes returns composites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bsdgames/+bug/725367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
