Milestone:  To Be Determined  |   Component:  program_options
  Version:  Boost 1.44.0      |    Severity:  Problem        
 Keywords:                    |  
------------------------------+---------------------------------------------
 program_options::parse_config_file() reads data from an ifstream instance.
 It updates the failbit value of this stream when the file reads are ok.

 Test case is attached :

 $ ./foo [[BR]]
 ios failure: failbit: 1 - badbit: 0[[BR]]
 perror() value : test.cfg: No such file or directory[[BR]]
 $ touch test.cfg[[BR]]
 $ ./foo [[BR]]
 opening test.cfg: failbit: 0 - badbit: 0[[BR]]
 let s call parse_config_file()...[[BR]]
 ios failure: failbit: 1 - badbit: 0[[BR]]
 perror() value : test.cfg: Success[[BR]]
