System Information
Operating system:

Blender Version
Broken:
(example: 2.79b release)
(example: 2.80, edbf15d3c0, blender2.8, 2018-11-28, as found on the splash screen)
Worked: (optional)

Short description of error
I set up several scenes, and one scene to composite the others into a single render. If I try to render from the Compositor scene, blender crashes. If I render each scene separately, no crashes.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
Load the attached .blend file.
Switch to the Scene called "Compositor".
Render Animation.

Not a crash but a render error:

Render error (No such file or directory) cannot save: '/Users/james/Documents/blender/render bin/0001.png'

Are you using the latest Blender 2.8 build of today's 2019-02-06?

Also no crash here.
@nacioss: you have to specify some existing output folder, if I do that I can render the whole sequence.

Works fine for me too.
As already asked, are you using an up to date blender beta?

Yes, I was using the downloadable beta of Feb 06, 2018.

Marco says I must "specify some existing output folder"....

In which scene? All of them?

Every scene in the .blend I submitted does, indeed, have an output folder specified. The folder exists. That's what I'm seeing when I reopen the file I sent you.

Here's an actual work file that exhibits the bug behavior. This crashes even after I've ensured that each Scene has an output path, specified to a folder that already exists.

{F6542645}

Open it,
Go to Compositor Scene,
Render Animation.

This is the actual work I was doing when I discovered the bug. I confirmed it moments ago, using the latest available blender beta as of 15:06 Eastern time today, Feb 07.

So you are can not reproduce the issue on the initial blend file in the bug report?
Or can you still reproduce it on the minimal example you provided at first?

I cannot reproduce it on the first .blend I sent, using the latest beta I have (from the latest available blender beta as of 15:06 Eastern time yesterday, Feb 07.). When I sent it to you, it crashed for me twice, but isn't doing it now. I just tested it again moments before clicking to send this message.

The 2nd file, however, exhibits the bug reliably. I just tested it again, too, moments before clicking to send this message. Blender crashes before rendering a complete, composited frame. Sometimes, it would render a frame or two, but mostly, it crashes before writing the first frame to a file, it seems to me.

I reproduced the crash 3 consecutive times today, using the 2nd file I sent, {F6542645} with today's download of blender 2.80 beta, on Friday, February 8, 2019. If there's something else that I can provide to you, or test for you, I'll be glad to do it.

I don't think this has to do with compositing.
I can reproduce the crash in the compositing scene.
But I can also reproduce it if I render re-imported GOOD angler scene
and then render 2nd crime TOON LINES.

As you can see, the crash happens in the rigid body physics system.
