On linux:

    ROOT /home/mnb20/src>./testgid 
    count = 2
    0 24 
    setgroups(0,NULL) succeeded
    count = 0

    gid = 8
    count = 0

With the program modified to not attempt the setgroups(0,NULL) I get:

    ROOT /home/mnb20/src>./testgid2 
    count = 2
    0 24 
    setgroups(1,grouplist) succeeded
    count = 1
    0 
    gid = 8
    count = 1
    0
