Please note that the ab= ove fix introduced a leak in getaddrinfo, for which a fix was just pushed in the master branch as commit ec6b95c3303c700eb89eebeda2d7264cc184a796. Direct gi= tweb link: https://sourceware.org/git/gitweb.cgi?p=3Dglibc.git;h=3Dec6b95c3303c700eb89= eebeda2d7264cc184a796 I guess Siddhesh will backport this leak fix in release branches all the way back to 2.34 after the commit will have spent some time in the master branc= h.
