Description:
        everytime the new bash forks a process, I got a 
        bash: invalid character 45 in exportstr for --
        this occurs on Solaris 7/Sparc.
        However, I also compiled the new bash on a Linux/intel
        and a Solaris 7/intel, and it works fine there.

        on all machine I have basically the same environment, including
        a - function :
bash> type -
- is a function
- ()
{
    popd "$@" >/dev/null && dirs -v
}                                       

Repeat-By:
        Looks quite obscure.

Fix:
        No idea.
