stap semantic error on PPC64 running Red Hat Enterprise Linux AS 4 Update 4

["S. P. Prasanna" <prasanna at in dot ibm dot com>]

Hi,

I get the following error "semantic error:
 duplicate probe point pattern" while running the tapset present
in /usr/share/systemtap/tapset/process.stp on PPC64.
Is the same error seen on other architectures too?
Am I missing something?
Details about the rpm's installed and error messges is as below.


Thanks
Prasanna
