Short description of error
When a shader on hair curves uses an attribute, like the surface_normal attribute in the example file, Blender can crash when the hair object is moved or animated.

It only seems to happen when the hair object is selected in Eevee render or material preview.

Exact steps for others to reproduce the error

Open attached file. Make sure the hair object is selected. Switch to rendered view and then play the animation. Blender should crash within a few seconds.
Playing the animation while shaders and still compiling crashed Blender immediately.
