While trying to run testsuite/systemtap.base/bz6850.stp on powerpc machine, stap
errors out.
Here are the details.
#file bz6850
./bz6850: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1
(SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for
GNU/Linux 2.6.9, not stripped
# stap -v -v -v bz6850.stp

Running rm -rf /tmp/stapceaG4O
However a 64 bit bz6850 does seem to face the same problem.

Is this a typo? s/does/doesn't/, per Srikar's 10/8/08 comment on bug 6850?

Verified that this patch fixes the problem of tracing 32 bit user applications.
