Please find a less complex example attached.

The output of readelf -Sl for the affected library.
libc-2.18.so.txt

The library is using a debug link to link to a file with the debug information.
libc-2.18.so.debug.txt

The command to run the script "taptrek_run_ZIX2.stp" is stored in "cmd.sh".

The output of executing "cmd.sh" is in "cmd-output.txt".

The folder "stap" contains the result of the stap run. I only removed
the already compiled object files to keep the size small.

Thanks,
Torsten
