| BASH PATCH REPORT |
| ================= |
| |
| Bash-Release: 4.3 |
| Patch-ID: bash43-032 |
| |
| Bug-Reported-by: crispusfairbairn@gmail.com |
| Bug-Reference-ID: <b5e499f7-3b98-408d-9f94-c0387580e73a@googlegroups.com> |

| Bug-Description: |
| |
| When bash is running in Posix mode, it allows signals -- including SIGCHLD -- |
| to interrupt the `wait' builtin, as Posix requires. However, the interrupt |
| causes bash to not run a SIGCHLD trap for all exited children. This patch |
| fixes the issue and restores the documented behavior in Posix mode. |
| |
| Patch (apply with `patch -p0'): |
