  Client side issue
  

Problem conclusion

• The conversion of an OLE object to a text version allocates a
  block of memory and then assigns that to a different type of
  string that makes a copy (which is memory and time inefficient
  of itself) and then abandons the first allocated memory - so
  every single OLE conversion leaks a chunk of memory that is not
  released until DOORS is closed..  Changing the copy to another
  string management type which takes ownership of the first buffer
  and correctly frees it when finished makes it all work.
