Function tracing not working

Thanks for your answer, that does help. However, I have now adjusted
the code so that sudo is not required, but when I import the trace the
UST-CallStacks are still strikethrough.

Any thoughts why this is happening?

I don't see any runtime errors whether or not I specify the prefix:

LD_PRELOAD=liblttng-ust-cyg-profile.so

Is that expected?
