Maybe I am not reading the simpler example correctly.
But it looked like it was still mixing user and kernel probes, used guru
mode and cross compiling. Are all of those factors needed to trigger the
bug?
If at all possible just one simple probe against libc.so to show what is
going wrong would be ideal.
