  11 Bug-Description:
  12
  13 When evaluating and setting integer variables, and the assignment fails to
  14 create a variable (for example, when performing an operation on an array
  15 variable with an invalid subscript), bash attempts to dereference a null
  16 pointer, causing a segmentation violation.
