   Priority:  major         |   Milestone:          
  Component:  SHP Provider  |     Version:  3.4.0

----------------------------+-----------------------------------------------
 The corrupted or invalid spatial index file can lead unhandled
 FdoException in destructor of class "ShpFileSet", as following:

 \Providers\SHP\Src\Provider\ShpFileSet.cpp

 ShpFileSet::~ShpFileSet (void)
 {
    if ( mFilesExist ){
      ReopenFileset( FdoCommonFile::IDF_OPEN_READ );

      .....
 }

 The function "ReopenFileset" will open the idx file and generate a
 FdoException when the idx file is invalid.
 This unhandled exception can lead application crash.

 You can modify the idx file deliberately to reproduce this problem.
 For example, use text editor to modify the first characters of this file
 as any others.
