Anyway I still have no clue and nobody has given me a straight "yes" or "no" answer...
An Airline like Air Canada cannot publish a fare PHL-YYZ-HNL. So by only plugging in PHL-HNL it should abend. It becomes a little more complex now that the fares are published as individual segments and if multi-city application is used, I can see it happening. It is likely that the overall calculation of taxes would cause the program to hiccup.
