Error description

• cleartool -diff pass thru option '-blank_ignore' may not report
  the differences correctly under certain conditions
  
  
  ClearCase 7.1.2.2
  
  
  Multiple UNIX OSes
  
  
  To Reproduce:
  
  1)  Make a new VOB and View
  
  
  2)  Make the following elements:
  
  $ cat cleartest_1
  ab
  
  
  $ cat cleartest_2
  a b
  
     NOTE:  The above is:  'a b'
         Meaning, there is one space within ?a b?'
  
  
  $ cat cleartest_3
  ab
  
  
  $ cat cleartest_4
     ab
  
     NOTE:  The above is:  '   ab   '
         Meaning, there are three spaces in front and three spaces
  behind the 'ab'
  
  
  $ cat cleartest_5
     a    b
  
     NOTE:  The above is:  '   a    b   '
         Meaning, there are three spaces in front and three spaces
  behind, including four spaces in the middle
  
  
  3)  Issue the following ?cleartool diff? commands:
  
  
  $ cleartool diff cleartest_1 cleartest_3
  Files are identical
  $ echo $?
  0
  
  
  $ cleartool diff cleartest_1 cleartest_2
  ********************************
  ??? file 1: cleartest_1
  ??? file 2: cleartest_2
  ********************************
  -------------[changed 1]---------------|-------------[changed to
  1]------------
  ab                                     | a b
                                        -|-
  $ echo $?
  1
  
  
  $ cleartool diff -options -b cleartest_1 cleartest_4
  Files are identical
  $ echo $?
  0
  
  
  $ cleartool diff -options -b cleartest_2 cleartest_5
  Files are identical
  $ echo $?
  0
  
  
  So, the problem is here:
  $ cleartool diff -options -b cleartest_1 cleartest_2
  ********************************
  ??? file 1: cleartest_1
  ??? file 2: cleartest_2
  ********************************
  bash-3.00$ echo $?
  1
  
  
  As you can see above, the differences were not printed.
  
  Workaround:  None
