Affected version:
curl-7.24.0
c-ares-config-1.8.0
git-1.7.9.6
>How-To-Repeat:
Compile curl with c-ares binding, and recompile git. It will failed to resolve dns when using http & https protocol, while through git:// protocol it will be able to resolve and continue to pull or push.
>Fix:
Recompile curl without c-ares and recompile git.
