I've found two bugs so far:


The first is a minor one. If the sieve depth is greater than 2^32, than the value stored in the headline of the output file doesn't match that one from the input file, e.g. 37572480860218 -> 106954810


The second one is a bit serious. I'm getting a ROUND OFF error while testing 3*2^234760-1:

Bit: 234759/234762, ERROR: ROUND OFF (0.5) > 0.40
Possible hardware failure, consult the readme file.
Continuing from last save file.

Seems that the FFT length (12K) may be choosen too small in this case, since this machine never caused a "possible hardware failure" before.

Nevertheless it's very very fast and I haven't found any non-matching residuals so far. Great job, George!
