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