Short description of error
After executing the "Make Static Override" operator on a linked armature, blender crashes upon entering pose mode.

Exact steps for others to reproduce the error
Start Blender with --enable-static-override.
Delete all default objects for an empty scene.
From File select Link, open the Brow-Particles.blend file and select Brow and biped_blenrig in the Objects folder.
Upon successful linking, select the armature and from the search menu, type and select "Make Static Override".
Enter pose mode and Blender crashes!

The linked mesh (Brow) which is deformed by the armature has vertex groups and combed hair particles.
I initially thought the issue is related to the hair system alone, but was able to successfully link and override another object with combed hair. So I wasn't able to fully isolate the crash to the hair system.

I have summarized my results based on three different file, with and without hair particles below.

Brow-Particles.blend => After linking and statically overriding Blender does crash.
Brow-NoParticles.blend => After linking and statically overriding Blender does not crash.
Mannequin-Hair.blend = > After linking and statically overriding Blender does not crash.
