commit b6b5fd494f997be314d154df49c4017db99dda34
Author: Stephan Bergmann <sberg...@redhat.com>
Date:   Wed Jan 24 16:41:22 2018 +0100

    Allocate ImplPointArray::mpArray as a true Point[]
    
    ...as the default Point ctor already zero-initializes its members, removing 
the
    need for the memset call (that causes -Werror=class-memaccess, "clearing an
    object of non-trivial type 'class Point'" with upcoming GCC 8).  Also use
    unique_ptr.

commit 2a727074012aaaa782f41b0f4470c95f095e030e

    Use std::fill instead of memset
    
    ...to avoid GCC 8 -Werror=class-memaccess ("clearing an object of 
non-trivial
    type ‘struct SwSrchChrAttr’").  Similar to
    <https://gerrit.libreoffice.org/#/c/48488/> "Allocate 
ImpXPolygon::pPointAry as
    a true Point[]", std::fill appears to produce adequate code here with recent
    compilers.
