Hello all, Running mprime 23.9.2 on my i686 Linux 2.44.22 (Fedora Core 1), I get a segfault after "stage 1 GCD"�:
[Oct 27 10:44] M34201171 stage 1 is 98.49% complete. Time: 769.143 sec. M34201171 stage 1 complete. 1096498 transforms. Time: 41811.942 sec. Starting stage 1 GCD - please be patient. Stage 1 GCD complete. Time: 186.462 sec. zsh: segmentation fault mprime -d If I restart mprime (I use "mprime -d"), it seems to start again with the P-1 factoring�: pc31 ~ $ mprime -d Mersenne number primality test program version 23.9 Starting P-1 factoring on M34201171 with B1=380000, B2=7125000 Chance of finding a factor is an estimated 5.07% P-1 on M34201171 with B1=380000, B2=7125000 But this factoring has already been done, with exact same values of B1 and B2. So, the two things I ask are: -- There seems to be a bug in the code; I don't think it is a problem with my computer, since it is heavily used for number crunching (one year of scientific computation almost full-time) and I never got any suspicious segfault. Can I do something to help you fix it? -- I'd like to reproduce it, but the program wants to do the P-1 factoring again. Is it normal? Shouldn't it be checkpointed somewhere? Since I'll have to wait 11 hours to eventually see the segfault again, I wonder if it's worth doing... Thanks for any help and/or explanations, and I hope I'm not too confused about what's going on.
