System crash with line cutter

Moved from r-lib/ragg#155

Interesting. Now I wonder if it could be confined to ggraph or if it's a peculiar way ggdag is using it

[thomasp85]

is ggdag doing anything outside of building up a standard ggraph plot in the end?

[malcolmbarrett]

Well, ggdag sort of goes around ggraph when it comes to the API. It uses ggplot() rather than ggraph(). Internally, it uses the Geoms from ggraph. I wasn't able to replicate this with ggraph itself, which made me think it might be something about this way that ggdag makes use of the edge geoms.

[thomasp85]

I can't see how that would be able to cause a system crash so it is more likely a bug latent in ggraph

[malcolmbarrett]

Oh I definitely think it's in that line cutting code, just maybe invoking it in a way that is not common in ggraph itself
