I also see this failure on x86_64:
uname -a
Linux 2.6.27-autokern1 #1 SMP PREEMPT Mon Oct 20 07:30:55 UTC 2008
x86_64 GNU/Linux
# ./testcases/bin/setgroups01_16
setgroups01_16 1 FAIL : setgroups(65536, list) Failed, errno=14 :
Bad address
But Passes fine:
# ./testcases/bin/setgroups01_16
setgroups01_16 1 PASS : setgroups(65536, list) returned 0
