A quick looks shows gcc doing partial inlining of foo. Some of the variables
might indeed not be available in the partial inlined version of foo that stap
probes. So it might actually reflect reality in this case of where the probe
gets placed. I think I just filed the testcase to do a deeper analysis of what
is going on.
