Something strange is happening here, probably a translator bug. The
"no match for probe point" message occurs if no "derived_probe"
instances get accumulated for a particular probe construct in the
script. But it should have been created. Debugging this may require
probing the messiest part of the translator: tapsets.cxx, starting
at(say) query_cu.
