stap --rlimit-stack=1 does not behave as expected in RHEL6.4

[Hien Nguyen]

Under RHEL6.4 and systemtap-1.8x, I run the rlimit.exp testcase, it 
failed this test

FAIL: rlimit STACK small


Upon looking under the hood, it looks like the test doing this and 
expecting stap to crash or fail.

exec stap --rlimit-stack=1 -p4 systemtap.base/rlimit.stp

However, stap did not crash and successfully built the stap-xxx.ko.

I saw a bug filed on this, but there is no follow up

http://sourceware.org/bugzilla/show_bug.cgi?id=13977

I wonder if anyone run into this same issue.

Thanks, Hien.
