On some platforms it outputs a "setpgid" error while on others it invokes an builtin "exit" or "output" command. Other users reported this behavior reoccurs. On the following distributions: - Debian Testing - Denian Sarge - Gentoo 1. exits with the "exit" builtin. On RH8 1. bash: child setpgid (12740 to 12732): Operation not permitted On SUN 1. bash: child setpgid (25730 to 25726): Not owner All the above with various kernel, bash and gcc versions.
