Comment 8 for bug 725367

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?
