Confirmed on MacOS 10.14 build a740cc53ea

The issue seems to be specific to the mesh in that file. If I add an icosphere or other mesh, sculpting tools work fine on that mesh. It is only when entering sculpt mode with the wing selected that it crashes.

Hm, seems to be tied to the scene [which just doesnt seem to have ToolSettings->sculpt -- you can inspect this in the Outliner Data API as well]

If I add a cube in this scene, go to sculptmode (without subdivision modifier -- or else it will crash, too) then ToolSettings->sculpt will get created.
After that you can happily sculpt on the wing as well (so nothing wrong with that mesh in particular).
Same if I just append the collection to a new file.

Not sure how ToolSettings->sculpt would ever get lost? [maybe just corrupted file?]

@Sergey: mind checkon on this one?

There are another model, that's made in previous version of blender (2.7) and blender crashes when any part of model switched to sculpting, for example
TempestShadowFig4.blend

It's seems, that's in latest build of Blender (version: 2.80 (sub 35), branch: blender2.8, commit date: 2018-11-30 00:46, hash: 4c31bed6b4) this issue is fixed.
