The crash apparently happens when rendering the text for the ruler (Timecore, Bar/Beat, Tempo ...).

Since you say "Zoom in past a certain level in the editor window with a certain region in view."
Can you tell us what the time position is? Perhaps a screenshot of the top of the editor window (clocks, and visible rulers) before you zoom in?

Removing the region from my project fixed the issue. If you still think it is the time position that's at fault, I can recreate the project and send a video of the crash, but from what you said it sounds like Ardour crashed trying to render a more detailed view of that region.
