I have contacted upstream and ask for help.
I guess the segfault is due to some bugs in the #threads detection code since we have: WARN: CY_THREADS = 8 exceeds number of cores = 6 WARN: At line 342 of file .././src/radix1024_ditN_cy_dif1.c: n_div_nwt%CY_THREADS != 0 but I am not absolutely sure. Yes, I think it is a good idea to call it 14.2~pre since some more bugs might get fixed on the real release. Thanks for the testing! I will reply when the issues are (believed to be) fixed. > > Meow!
