I checkout the latest CVS. After compilation and installation, guess
what? It WORKS.
No seg fault. And the it says "hello world" to me. :-)

I should have tried the latest CVS at first. Then, it seems that the
snapshot of
ftp://sources.redhat.com/pub/systemtap/snapshots/systemtap-20070317.tar.bz2
has something wrong.

Thanks to FChE and Martin who help me to debug this problem.
