(Hopefully) Final version. Now it really builds correctly.

Ups, sorry, missed second commit to res_init.c.

Now, I have build process finished, and I am waiting for rpms to be built in
next two hours. I hope now leak should be really fixed.

Comment 4 Jakub Jelinek 2006-12-13 12:13:34 EST

This is too risky this late in RHEL3 release cycle and there is a workaround
available.  E.g. addition of __res_iclose@@GLIBC_PRIVATE will cause failures
during upgrades for system daemons that are started before the upgrade and dlopen
libresolv after glibc upgrade (e.g. as part of gethostby* or getaddrinfo call).
