[Octave-bug-tracker] [bug #37591] system with async option results in zombie processes

[Dan Sebald]

Follow-up Comment #6, bug #37591 (project octave):

Actually, the shell "sh" probably is exiting with "-c" option.  The following
terminal commands should illustrate:


sebald@ ~/octave/octave/octave $ sh
$ exit
sebald@ ~/octave/octave/octave $ sh -c "ls"
aclocal.m4
sebald@ ~/octave/octave/octave $ 


However, the execl documentation states:

"
Return Value

The exec() functions only return if an error has occurred. The return value is
-1, and errno is set to indicate the error.
"

So, I've placed ";exit 1" at the end of the command.  That definitely causes
different behavior, with error messages, but it still doesn't get rid of the
forked processes.
