APAR status

  • Closed as program error.

Error description

  • If you are reading from a stream and puting the contents into an
    integer, if you read beyond the end of the file, DOORS will
    crash.
    
    This was introduced at some point between 8.3.0.2 and 9.1.0.0.
    
    To recreate:
    
     - run the following code, where empty.txt is an empty file:
    
    '
    Stream s = read 'C:\\empty.txt'
    int line
    
    s ?? line
    '
    
    Workaround:
    Before reading each line, make sure the condition 'if (!end of
    s)' is satisfied.
