[0.17.34] ERROR: Factorio crashed due to Stack overflow. when working with electric power poles

[edavis6678]

I was re-routing electrical in a few large Solar fields, (ie. cleaning up poles and the electrical network in general), when Factorio crashed.

I believe the act of disconnecting and reconnecting the large power source from the network (1.4 million panels in total), and re-attaching quickly may have some factor. It can be easily recreated on demand.

Log files and game save here: https://drive.google.com/open?id=1tcfSB ... OedP5R6nub

Let me know if you need any additional information as I can recreate it. I don't think most people will have a solar field this big, but maybe something worth a look into.

Running Vanilla, no mods. (server is running on headless Ubunto/Linux)

Thanks for the report and the save file. I was able to reproduce the crash and it's now fixed for the next version of 0.17. It's still quite slot to add/remove that electric pole but it doesn't crash.

I have some ideas about how to make it faster but those will have to wait for some future time.

It's been my dream to make it to the patch notes!! Only took over a million solar panels to do it lol

I"m glad you were able to figure it out.
