System Information
Operating system: Arch latest
Graphics card: GTX 1080 Ti x 2

Blender Version
Broken: 2.80 ecdd1864d1

Short description of error
When working with more than one node, such as Alpha Over, adding a keyframe in any of the conventional ways crashes Blender... at least on the Fac attribute (Premult seems fine). This is true whether the node is connected, or not.

Exact steps for others to reproduce the error

Open Compositor Node Editor
Add any input node (Image Node is as good as any)
Add an Alpha Over node and insert keyframe to the Fac attr (should be fine)
Add another Alpha Over node (or duplicate existing one); insert keyframe
CRASH!!!

Based on the default startup or an attached .blend file (as simple as possible).

I can't reproduce this on my end.

Could you upload a simple .blend file where I can just open it and insert a keyframe and it should crash?
Just to double check that I'm not missing something.

Sure. It would appear as though it occurs with Image Sequences, in particular. I've included a packed .blend file with a simple node set-up to demo the crash. Just change one or all of the Image nodes to Image Sequence and add a keyframe to Fac on the third Alpha Over node. It'll crash.BL-2.80_compositorFacCrash.blend
