11 Bug-Description: |
|
12 |
|
13 When bash is running in Posix mode, it allows signals -- including SIGCHLD -- |
|
14 to interrupt the `wait' builtin, as Posix requires. However, the interrupt |
|
15 causes bash to not run a SIGCHLD trap for all exited children. This patch |
|
16 fixes the issue and restores the documented behavior in Posix mode. |
