      Upstream in glibc, we fixed a code generation issue with later GCC versions which break certain common coding patterns involving socket addresses. We should consider backporting this commit:

    socket: Use may_alias on sockaddr structs (bug 19622)
    
    This supports common coding patterns.  The GCC C front end before
    version 7 rejects the may_alias attribute on a struct definition
    if it was not present in a previous forward declaration, so this
    attribute can only be conditionally applied.
    
    This implements the spirit of the change in Austin Group issue 1641.

      GCC 11 should benefit from this, too, and GCC Toolset even more so.
