Hello, FYI, I have unbound 1.4.0 configured with --with-libevent on linux kernel 2.6.29 x86_64. The compile process was smooth, but I got the following error when starting unbound : unbound[30520]: segfault at 10 ip 00007f8e599deb61 sp 00007f8e58c2c020 error 4 in libpthread-2.10.1.so[7f8e599d6000+16000] The error dissapeared in 1.3.4. Thank you. Regards, Asfihani
