--- Comment #2 from DIL <liakhdi at ornl dot gov> --- No, at this point I do not, unfortunately. These OOP bugs tend to show up at higher levels, so it is not always clear how to reduce it to something small. I will try to reduce it to something smaller, but not sure how far. For example, the current problem shows up in the implementation of a vector container (gfc_vector.F90), but only when it is used to implement something more complex, specifically the graph container in this case (gfc_graph.F90). The latter uses three containers in its implementation: vector, list, and dictionary, so it depends on all of those.
