In V3.8.16, a roundoff error after taking the next FFT length causes an abort, which is also bad... The solution is simple : I can test the number of fft increments, and will abort if it is too large (5 for example). I will implement that in the next release... Regards, Jean

I hope George can also fix the other bug in gwnum with the false negative prime.

A bug (old? new?): 10^523610^26181
I found a weird "glitch" in the latest LLR. (Pun intended, actually, this is what the Numberphile folks called, in part, the 10^{2n}10^{n}1 numbers).
10^523610^26181 is a prime but you wouldn't know it from the LLR's output! If one scans as usual the lresults.txt files for "" or "[^t] prime", they will not find it. Instead, this is what is produced: Code:
10^521410^26071 is not prime. RES64: 36873FC14B1F7A51. OLD64: A395BF43E15E6EF0 Time : 731.109 ms. 10^522610^26131 is not prime. RES64: D1632ECDC01349A0. OLD64: 74298C694039DCDE Time : 734.097 ms. 10^523210^26161 is not prime. RES64: 4528B319791091AD. OLD64: CF7A194C6B31B505 Time : 734.850 ms. Giving up after 11 restarts... Time : 18.224 sec. 10^524410^26221 is not prime. RES64: C2E6D3A70522D18E. OLD64: 48B47AF50F6874A8 Time : 724.714 ms. 10^524610^26231 is not prime. RES64: 699CEEBDCA51AC52.
