On amd64, clang++ 4.0 uses the MOVAPS SSE instruction to initialize
sufficiently large objects returned by the "new" operator.  This
requires that the object have 16-byte alignment.  The FreeBSD
malloc() implementation does the correct thing here, but OpenOffice
has a couple of internal memory allocator implementations that only
align to 8-byte boundaries at most.  In addition OpenOffice overrides
the new operator to interpose a couple of layers of wrappers.  If
the --enable-debug option is passed to configure, the wrapper adds
8 to the size passed to the allocator and adds an 8 byte offset to
the pointer returned by the allocator to make room for a signature
that it adds to the beginning of the memory block (the signature
is validated and the inverse transformation is done when the memory
is freed).  This breaks the proper alignment done by the mamory
allocator.  Fix these problems by adding an EXTRA_PATCH that teaches
the internal OpenOffice memory allocators to do 16-byte alignment
