[Bug translator/6946] New: stap unable to resolve probe points for 32 bit user space apps on PPC64 arch.

While trying to run testsuite/systemtap.base/bz6850.stp on powerpc machine, stap
errors out.
Here are the details.

Running rm -rf /tmp/stapceaG4O  

However a 64 bit bz6850 does seem to face the same problem.
