| 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. |
---|
