I tried the latest CVS, and found it will crash my ppc64 box on both
2.6.17/2.6.18 kernel immediately after Pass 5. This should be introduced during
recent checkin since I had no problems played with stap only one or two days ago.
Here is the xmon message:

I changed the subject. staprun shouldn't cause the system crash.
I tried the latest CVS on i386/2.6.18.1 and x86_64/2.6.18.1, and they all worked
well. So it seems that this is a ppc64 specific error.
