1 | BASH PATCH REPORT |

| 11 | Bug-Description: | |
| 12 | ||
| 13 | When `printf -v' is used to set an array element, the format string contains | |
| 14 | `%b', and the corresponding argument is the empty string, the buffer used | |
| 15 | to store the value to be assigned can be NULL, which results in NUL being | |
| 16 | assigned to the array element. This causes a seg fault when it's used later. | |
| 17 | ||
