System Information
Operating system: Windows-10-10.0.18362 64 Bits
Graphics card: GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 436.02

Blender Version
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-12-04 11:32, hash: f1aa4d18d4
Worked: (optional)

Short description of error

Randomly certain frames will fail to render anything because the FreeStyle module code fails see Console output for insight into issue.
Consider ways to harden the code in those situations/location. Looks like a perfect example of a type checking issue is my first guess.

Line is Double 13s how sinister.

Exact steps for others to reproduce the error
You can't reproduce this with steps, without f'in around for hours if not days. Alas you could think about why this error occurs on that line before dismissing yet another bug report...
I know you always overlook bugs with lame excuses like I couldn't reproduce this please add more of your time so I don't have to think about this professionally, so I am just bringing awareness to lame code with bugs (C related). I think hardening is needed in that code, and this is enough information so please don't ask me for anything more. I've done my part. Thanks for leaving ego out of this and being a useful coder.
This is a good example of why Blender can't be used professionally. Use it as an example for all devs to review all Blender code. I have run into at least 4 other situations where Blender completely crashes I couldn't be bothered to report because no error found, but this one has an error in the console (because it doesn't completely crash).

Okay I can add something here (apologies for Rant offered).
This fails to generate frames with Freestyle Line Style Modifier "Bezier Curve" with an error of 3.800 not that that value has anything to do with it.
was 4th in a stack of Sampling, Backbone, Guiding Lines

The error could be separate from that in fact so not sure myself. So confusing and complicated on top of convoluted is all the Freestyle stuff.

Definitely Frustrating! I am hopeful my minimal efforts result in Blender being more reliable for others too.

@MasterJames I can understand your frustration but there is nothing a developer can do without a file to reproduce the issue.

Also your rant is a waste of everyone's time. It gets on the way of looking at the issue. If you think a previous report from you was triaged unfairly please contact me directly and I can take a look (dalai@blender.org). But I couldn't find any evidence of that in your previous reports (checked briefly only).

I will close this report since the alternative would be for me to edit the task description and remove all the rant which would resonate even worse with you I suppose.

For now I kindly ask for you to focus on the second issue you reported, since it is more reproduceable, and open a new report for it follow the guidelines (there is nothing we can do without a .blend, and please be concise on the report). Hopefully a fix to the latter also fix your original issue.
