Doc Type:	Bug Fix
Doc Text:	Resolution for gcc compatibility issue with "sockaddr_in" The default RHEL 6 compiler has rules about how to copy "struct sockaddr_in" that are substantially different to those used by later versions of gcc (E.g. the tools provided with Red Hat Developer Toolset). This caused corrupted sockaddr_in overlays when using newer compilers. This update changes the way the "unused" portions of the sockaddr_in structure are defined. Now, newer versions of gcc will copy them correctly. Note that -fno-strict-aliasing is still required for compiling such sources.

Description Florian Weimer 2016-05-23 04:50:27 EDT

+++ This bug was initially created as a clone of Bug #1337291 +++

The current struct sockaddr_storage definition causes problems with GCC 6 which are not fixed by -fno-strict-aliasing.  We need to backport a definition which compensates for this.
