Re: [Pdns-users] PowerDNS (2.9.22) crash with signal 8 (floating point exception)
Bert, BTW, I have compiled pdns from sources (2.9.22, the last one) as following: ./configure --prefix=$PWD/distr --enable-static-binaries --enable-shared=no --enable-verbose-logging make And replaced /usr/sbin/pdns_server with new executable. All works fine. Not sure I understand what is happening.

Yes, but result is still the same with pdns-static from website (centos 5.5, x86_64). But I did some more. Please notice, if I compile pdns by myself, just ./configure make make install, I have no problems. -- Thanks, Lyfar Dmitriy ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users
