- 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.
