Package: bash Version: 3.0-14 Severity: normal Hi, Bash accept negative exit status, I don't now if it is normal (dash or posh don't accept it.)

The exit status is anded with 0377, see exit(3). Ok, may be it could be nice to add it in bash man page. I still wonder if it is valid for POSIX mode as it is not supported by dash and posh. If it is ok, may be a bug report should be filled for dash and posh... Regards, Matthieu -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
