| BASH PATCH REPORT |
| ================= |
| |
| Bash-Release: 5.0 |
| Patch-ID: bash50-018 |
| |
| Bug-Reported-by: oguzismailuysal@gmail.com |
| Bug-Reference-ID: |
| Bug-Reference-URL: https://lists.gnu.org/archive/html/bug-bash/2019-10/msg00098.html |
| |
| Bug-Description: |
| |
| In certain cases, bash does not perform quoted null removal on patterns |
| that are used as part of word expansions such as ${parameter##pattern}, so |
| empty patterns are treated as non-empty. |
