Buggy source:

Fixed version (ground truth):

  int numHeadersAndPlaceholders=getHeadersCount() * mNumColumns;
  if (position < numHeadersAndPlaceholders) {
    View headerViewContainer=mHeaderViewInfos.get(position / mNumColumns).viewContainer;
    if (position % mNumColumns == 0) {
      return headerViewContainer;
    }
 else {
      convertView=new View(parent.getContext());
      convertView.setVisibility(View.INVISIBLE);
      convertView.setMinimumHeight(headerViewContainer.getHeight());
      return convertView;
    }
  }
  if (position < numHeadersAndPlaceholders + mAdapter.getCount()) {
    final int adjPosition=position - numHeadersAndPlaceholders;
    int adapterCount=0;
    if (mAdapter != null) {
      adapterCount=mAdapter.getCount();
      if (adjPosition < adapterCount) {
        convertView=mAdapter.getView(adjPosition,convertView,parent);
        convertView.setVisibility(View.VISIBLE);
        return convertView;
      }
    }
  }
  final int lastRowItemCount=(mAdapter.getCount() % mNumColumns);
  final int emptyItemCount=((lastRowItemCount == 0) ? 0 : mNumColumns - lastRowItemCount);
  if (position < numHeadersAndPlaceholders + mAdapter.getCount() + emptyItemCount) {
    convertView=mAdapter.getView(mAdapter.getCount() - 1,convertView,parent);
    convertView.setVisibility(View.INVISIBLE);
    return convertView;
  }
