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.
|
|
|
