fix integer overflows when computing crossing matrices (!3233) · Merge requests · graphviz / graphviz

Matthew Fernandez requested to merge smattr/graphviz:smattr/4e38eb11-8ed4-4075-b591-3abfc833070e into main May 15, 2023

Coming out of the discussion on #1488 (closed).

We should perhaps discuss whether an API break is worth it for this academic fix – we don’t have evidence that any graph that experienced these integer overflows is actually processable after fixing them. On the other hand, maybe we should rip the band aid off and do a more pervasive size_t migration for Graphviz 9.
