Hi, with locally compiled version: tinc version 1.1pre14-65-g93584bc I'm getting repeated segfault: [Thu Jun 8 08:39:02 2017] tincd[556]: segfault at 7ffdb77d0000 ip 00007f68ea77c194 sp 00007ffdb77cd4c8 error 4 in libc-2.19.so[7f68ea6ea000+1a2000] [Sat Jun 10 21:18:10 2017] tincd[7625]: segfault at 7ffc8c852000 ip 00007ff298de7194 sp 00007ffc8c84e928 error 4 in libc-2.19.so[7ff298d55000+1a1000] This is on a Debian 8.5 Similar on Debian 9: tinc version 1.1pre14-63-g3d8a836 [Fri Jun 9 23:06:33 2017] tincd[7288]: segfault at 7ffd44147000 ip 00007feb1e8bbb84 sp 00007ffd44142fe8 error 4 in libc-2.23.so[7feb1e82e000+197000] I'm not great at this kind of debugging, but if someone want's to give me pointers as to how to proceed, happy to do it. Thanks K.
