--- Comment #3 from Stan Cox <scox at redhat dot com> ---
I notice if the first dyninst run is via stap:
% stap -e 'probe process("/lib64/libc.so.6").function("usleep") { println("hi")
exit() }' -x `pgrep -f tst.x` --dyninst -k -vv
and if subsequent runs were directly via stapdyn then it worked okay:
% stapdyn -v -x 8955 /tmp/staprclqlD/stap_8970.so
stapdyn: found target "/usr/lib64/libc-2.28.so" in pid 8955, inserting 1 probes
