Comment (by cypherpunks2):

 {{{
 static LPBYTE generate_icon_group(IconGroup icon, IconPairs order, bool

 {
   LPBYTE group = new BYTE[
     sizeof(IconGroupHeader) // header
     + order.size() * SIZEOF_RSRC_ICON_GROUP_ENTRY // entries

   IconGroupHeader* header = (IconGroupHeader*) group;

   header->wReserved = 0;

   header->wCount    = FIX_ENDIAN_INT16((WORD)icon.size());

   order = sort_pairs(order, first);

   for (IconGroup::size_type i = 0; i < icon.size(); i++)
   {
     RsrcIconGroupEntry* entry = (RsrcIconGroupEntry*)
       &group[sizeof(IconGroupHeader) + SIZEOF_RSRC_ICON_GROUP_ENTRY * i];

   return group;

 {{{

 Why?

 order.size() == icon.size()? How?

 ZeroMemory for group need.
