Solution

 Top
This correction prevents crashing (because wrong ifdef) and additionally prints out the index or sub-index root in 77 only. One root cause might be solved by http://pts:1080/webpts?wptsdetail=yes&ErrorType=0&ErrorID=1182089 In cbd500_Tree::bd510_PrepareOrderExecutionOnNextHigherLevel() the left neighbor check is wrong if the left neighbor must be determined and is not already known because if checking the right the current node is moved to the right neighbor. Now all three nodes are dumped if the separator is not found and the left neighbor is determined correctly. DataIndexTrace 1 and DataIndexCheck 1 prints out additional traces.
