drill and GCC11 #131

Closed stanislavlevin closed 2 years ago

stanislavlevin commented 3 years ago

Recently Fedora34 has been released. This distro switched to GCC11 from GCC10. The drill tool compiled with GCC11 doesn't work as it worked compiled with GCC10.

Sig chasing error:

[root@master1 /]# drill -r ./roots -S -k /etc/trusted-key.key_ dnssec. @127.0.0.1 SOA ;; Number of trusted keys: 1

Build with "-O2 -Wextra -Wstrict-aliasing=1" against develop branch (this project) is attached. build.log

Build with -fno-strict-aliasing fixes the problem:
