Error description

• cleartool chtype fails with 'Internal error #9 (../bdtm.c:677)'
  when changing element with consecutive identical versions
  
  
  ClearCase 7.1.x and 8.0
  
  
  Multiple UNIX and Linux
  
  
  
  To Reproduce:
  
  1)  Make a new branch: cleartool mkbrtype test-chtype
  
  2)  Modify the config spec for an auto-mkbranch rule off of
  /main for the new branch type created
  
  3)  Create a new element of element type of ?file? off the
  mkbranch rule config spec
  
  4)  Make several binary versions greater than 25MB per version
  
  5)  On the last version, checkin identical
  
  6)  Verify the md5sum matches:
  
  cleartool lsvtree -a test.so | xargs digest -a md5
  (test.so@@/main/test-chtype/0) = ***
  (test.so@@/main/test-chtype/1) = ***
  (test.so@@/main/test-chtype/2) = ***
  (test.so@@/main/test-chtype/3) = ***
  (test.so@@/main/test-chtype/4) = ***
  (test.so@@/main/test-chtype/5) = *** <- Match /7 and /8
  (test.so@@/main/test-chtype/6) = ***
  (test.so@@/main/test-chtype/7) = *** <- Match /8 and /5
  (test.so@@/main/test-chtype/8) = *** <- Match /7 and /5
  
  7)  Try and chtype the element to a binary_delta_file:
  
  cleartool chtype binary_delta_file test.so
  Change version manager and reconstruct all versions for
  'test.so'?  [no] yes
  create_version: Error: Internal error #9
  (/vobs/atria/lib/mgrs/binary_delta/bdtm.c:677)
  cleartool: Error: Type manager 'binary_delta' failed
  create_version operation.
  cleartool: Error: Unable to change type of element 'test.so' to
  'binary_delta_file'.
  
  
     NOTE:  As a test to verify, a hex editor was used to change
  one byte within the version 8 of the element from a lower to
  uppercase letter [for example, ?f? to ?F? (thus keeping the
  container the same size)] for test.so@@/main/test-chtype/8:
  
  cleartool chtype binary_delta_file test.so
  Change version manager and reconstruct all versions for
  'test.so'?  [no] yes
  Changed type of element 'test.so' to 'binary_delta_file'
  
  
  
  Workaround:  None
