I've tried pfiles.stp on the following kernels without any problems:

kernel-2.6.32-573.el6.ppc64
kernel-2.6.32-621.el6.ppc64

What kernel/arch did you see the problem on?

I've now tried this on 2.6.32-573.el6.x86_64 with no issues. I'm going to need
an exact kernel version where you saw the failures to be able to track this one
down.

For stap 2.7 as distributed with rhel6.7ish:

% uname -a

% stap -V

But git stap against the git pfiles.stp does work.
So does stap-2.7 against the same pfiles.stp.

I must have run newer stap against older pfiles.stp by mistake.  Sorry!
